Pay It Forward is an act of kindness that will change a person's life.

My Pay It Forward act of kindness was donating food to Siloam Mission(My original plan was to personally give each person food). I chose to do this particular activity because, at the time it was close to Christmas, and the theme of Christmas is to give. As I said before, I was donating food to the Siloam Mission Homeless Shelter, so obviously I'm helping people who are experiencing homelessness. What I did to do this task was really just asking the supervisors if I could donate some food. They said of course, and told me to put the food in the kitchen. After that, I thanked them, they thanked me, and I was done with it. This activity was done on Saturday, 21st of December.

When, and after I did this, I felt...good. I also kind of felt proud for myself,considering this is something I actually have never done before, and that I spent MY own money on this food. But hey, like I said, it's good to give. Naturally, I am pretty generous, if I do say so myself, but that's besides the point.

Unfortunately, I could not interact with the people, and therefore, could not find out their reactions, nor ask them to pay it forward. Which sucks, but donating the food is the best that I could do in my ability.

### Comparing and Ordering Fractions

**COMPARING AND ORDERING FRACTIONS**Let's start with ordering fractions first.

I am assuming you know what fractions are, so let's skip that part.

__ORDERING FRACTIONS WITH LIKE DENOMINATORS:__

When ordering fractions with LIKE denominators (the bottom part is the same in both fractions), all you have to do is order the numerators (the top part of the fraction)!

For example:

Let's say we have the fractions, 5/10, 3/10, and 8/10. All the denominators are the same. Now lettuce order them from smallest to largest!

Since the denominators are the same, all we have to do is order them by the numorator. (We do this because the smaller the numerator, the smaller the fraction.)

3/10, 5/10, and 8/10!

Viola! That is how you order fractions with like denominators!

__ORDERING FRACTIONS WITH UNLIKE DENOMINATORS:__

This is where things may get a little tricky.

When ordering fractions with unlike denominators, you have to multiply the fraction by 1. (a number over itself, eg. 1/1, 2/2, 3/3, etc.)

'How is this done?' you may ask.

How about a diagram?

Let's start easy. How about, 4/5 and 7/10?

To start off, what do both of these denominators have in common? Yes, 10. 7/10 already has 10 as it's denominator, so we won't have to change it!

To get from 5 to ten, we multiply by two.

*note we also have to change the numerator because we multiply by 1.

4 2 8

- x- =-

5 2 10

Now we have the fraction, 8/10, that used to be 4/5.

Remember that we had to order fractions?

Now that we have two numbers with the same denominator, we can do exactly what we did before with like denominators!

The answer is 7/10, 8/10

VIOLA! You now know this as well!

__COMPARING FRACTIONS:__

When you compare fractions, you basically compare!

When comparing fractions, you find the difference between them. This is like ordering them to see which one is larger, and which isn't.

So when you have fractions like this: 3/5 and 1/5

You can order them and see which is larger and which is smaller.

1/5 is smaller than 3/5.

VIOLAAAA! You know how to compare now too!

That was my short lesson on Comparing and Ordering Fractions.

*phew.*

Note: Okay, okay, okay. I know this is totally late. My bad.

Mathematically and Scientifically yours,

Nicole :D

Ps. That diagram did not go well as I intended to.

### Order of Operations

3 + 4(6-2) ÷ 2 =

I determined the answer by using "B.E.D.M.A.S."

Brackets: 6 - 2 = 4

Exponents: There are no exponents used in this question.

Division: 4 ÷ 2 = 2

Multiplication: 4(4) = 16

Addition: 3 + 16 ÷ 3 = 11

Subtraction: There is no subtraction used in this question.

The answer to the question is 11.

3 + 4(6-2) ÷ 2 = 11

### Comparing and Ordering Fractions

Comparing:

When you are comparing fractions you are trying to see the difference in then, by the amount.for example if you had 4/5 and 3/4 you have to find a common denominator to see which one is bigger. The common denominator would be 20. You multiply the numerator by 5 and then the denominator by 5. The fractions you should get are 16/20 and 15/20. Now take a look at them and see which one is bigger. 16/20 is bigger and reduced is 4/5. So 4/5 is you biggest fraction out of these 2.

Ordering Fractions:

When ordering fractions it is very simple, these are the fractions:

3/4, 4/5, 1/2 from least to greatest.

Find a common denominator and then multiply the denominator and the numerator by a number to get to the common denominator, like this:

3/4, 4/5, 1/2 20- common denominator

3/4 x 5 = 15/20

4/5 x 4 = 16/20

1/2 x 10 = 10/20

Now put them in order from least to greatest or greatest to least, whatever the instructions tell you to do.

10/20, 15/20, 16/20

Remember to put them back to their original fraction.

1/2, 3/4, 4/5

When you are comparing fractions you are trying to see the difference in then, by the amount.for example if you had 4/5 and 3/4 you have to find a common denominator to see which one is bigger. The common denominator would be 20. You multiply the numerator by 5 and then the denominator by 5. The fractions you should get are 16/20 and 15/20.

3/4 x 5 = 15/20

4/5 x 4 = 16/20

1/2 x 10 = 10/20

Now put them in order from least to greatest or greatest to least, whatever the instructions tell you to do.

10/20, 15/20, 16/20

Remember to put them back to their original fraction.

1/2, 3/4, 4/5

__Subtracting Fractions__

Common Denominator (Proper/Improper Fraction)- Subtract the numerater and leave the denominator as it is. Then divide the numerator by the denominator to get a mixed fraction if the fraction is improper.

Uncommon Denominator (Proper/Improper Fraction)- Times one or both fraction to get the same denominator. Then times the numerator by what you times your denominator. After that, subtract the numerator and leave the denominator as it is. Then divide the numerator by the denominator to get a mixed fraction if the fraction is improper.

Mixed Number, common denominator(Proper/Improper Fraction)- Times the denominator by the whole and add it to your numerator to get your improper fraction. Do the same thing with the other fraction if it has mixed numbers. Subtract the numerator and leave the denominator as it is. Then divide the numerator by the denominator to get a mixed fraction if the fraction is improper.

Mixed Number, uncommon denominator(Proper/Improper Fraction)- Times the denominator by the whole and add your numerator to get your improper fraction. Do the same thing with the other fraction if it also a mixed number. Times one or both fraction to get the same denominator. Then times the numerator by what you multiplied the denominator by. Subtract the numerator and leave the denominator as it is. Then divide the numerator by the denominator to get a mixed fraction if the fraction is improper.

### Mixed and Improper Fractions

Mixed fractions are numbers that have a whole and a fraction together. (Ex. 1¼, or 3½). Whereas improper fractions are fractions where the numerator is more than the denominator (Ex. 12/6, 7/2, 10/4)

To convert a mixed number to an improper, you need to do these steps:

(Let's say convert 4¼ to an improper fraction)

_________________________________________________________________

And that is how you convert mixed fractions/numbers to improper fractions.

To convert an improper fraction to a mixed, you can do these steps:

(The number is...18/4)

To convert a mixed number to an improper, you need to do these steps:

(Let's say convert 4¼ to an improper fraction)

- First, you need to know that the whole would be something like 4/4. So the question is 4 wholes.
- Then multiply the wholes by the denominator, that will show you how many there will be. So 4 x 4 = 16.

_________________________________________________________________

And that is how you convert mixed fractions/numbers to improper fractions.

To convert an improper fraction to a mixed, you can do these steps:

(The number is...18/4)

- Find out how many times the denominator would fit into the number (18), by dividing the numerator by the denominator. (
~~4 wholes,= 16 pieces.)~~ - Then, after dividing it. You will see a decimal point after, which means what is left. (Which is 2 in this...) which equals 2/4.
- Then add the whole and the fraction together. (4+2/4 = 4 2/4)

- If, the number ends up being something like 4 2/4, then you have to turn it into lowest terms. With even numbers you just divide it by 2 then continue till you get to lowest terms. (4 1/2 is lowest terms by the way.)
