It helps if you turn them into decimals first, then subtract (just remember that a whole number has 0's after a decimal point, it doesn't make any difference to a whole number if it has a decimal point with 0's after it or no decimal point!). But you can also do it like this (here is an example) 20 - 3 4/5 First you have to remember the a whole number = 5/5 or 4/4 or 66/66 ect. So now you can say 20 5/5 - 3 4/5 Do the whole numbers first: 20 - 3 = 17 Then the fractions: 5/5 - 4/5 = 1/5 Add 17 and 1/5 and you get 17 1/5 Hope these methods help!

How do your borrow from a whole number when subtracting fractions?
A mixed number has a whole number and a fraction. A fraction is a number that is less than whole and that has a denominator underneath a numerator. To add or subtract mixed numbers, add or subtract the fractions, then add or subtract the whole numbers. If the fraction portion of a mixed number, such as 2 5/6, is more than the fraction portion of the mixed number you're trying to subtract from, such as 3 1/6, you must borrow from the whole number of the mixed number you're trying to subtract from to make its fraction bigger...
