Mixed fraction is the same step for improper fractions. First if there is more numerators than denominators you multiply the the denominator by the numerator by how many times the denominator goes into the numerator.
example: if you multiply 10 into 21 the mixed number becomes 2 and the fractions becomes 1/10.
Also if the mixed fraction has a fraction(s) that can be divided 2 or more (this is called lowest terms).
example: 3 5/10 = 3 1/2 (5 is halve of ten).
If you have a mixed fraction and the numerator and denominator are the same this is also putting it in lowest terms. (When they are the same it equals 1 whole).
example: 3 3/3= 4
Improper fractions is a numerator that is higher than the denominator. You have to put it in lowest terms by how many times the denominator can be multiplied into the numerator. The number of denominator that multiplied into the numerator becomes a mixed number while the rest of the numerator becomes the new fraction.
example: 225/50 50x40=200=4 25/50=4 25/50 (lowest term) 4 1/2
If the denominator can be multiplied to equal the numerator it just becomes a whole number.
