Subtract fractions and then subtract the whole numbers. Sometimes you may need to borrow from the whole number. Ex: 3 1/4 - 1 3/4 (3 1/4 would be written as 2 5/4) so the equation would be 2 5/4 - 1 3/4 = 1 2/4

What is a like mixed number?
A mixed number is a whole number combined with a fraction like 3 7/9. (That was just a random example). A like number is a number that had the same denominator (the bottom or right number of the fraction) as the other fraction like 2/9 and 3/9. So like mixed number is a mixed number that has the same denominator as the other number.
What do you notice about the denominator when subtracting like fractions?
By the definition of like fractions, the denominators are the same.
Do you have to regroup mixed numbers that have like denominators when subtracting them?
No
Before adding or subtracting Why are fractions turned into like fractions?
They have to have the same denominator.
What is a common denometer?
When adding or subtracting fractions with different denominators, it is necessary to find a common denominator to solve the equation. A common denominator is like a common multiple, except its function is as the bottom number in a fraction.
How do you subtract mixed numbers and borrow from the whole number?
you subtract mixed numbers by changing them to improper fractions. to borrow from a whole number you take away one like 5 changes to 4 and then you change look to the other mixed number your subtracting by and write its denominator as 4s denominator.

How do you take a fraction and make it a whole number or a mixed number?
to make a fraction a mixed number..... you see how many times the denominator goes into thew numerator. after you do that you put what's left over than that becomes your new numerator,(the mixed number is going to have the same denominator as the fraction).so for example.......12 5------- = 1 -----
What is the improper fraction and the mixed number?
An improper fraction, like 22/7, is when the numerator is greater than or equal to the denominator. A mixed number, like 4 and 1/2, combines a whole number with a proper fraction.
How is dividing mixed numbers the same as dividing fractions?
A mixed number can be converted into an improper fraction. Mixed numbers as improper fractions can be divided just like any other fraction. To convert a mixed number to an improper fraction multiply the whole number by the denominator and add the original numerator to give the new numerator and put this over the original denominator.
