3+4(6-2)divided by 2=

i solved the answer using BEDMAS


Brackets: (6-2)=4


Exponents: no exponents


Division: 4 divided by 2= 2


Multiplication: 7x4= 28


Addition: 3+4=7


Subtraction: no subtraction


now add it all up

7(4)divided by 2= 14

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,

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
