SUBTRACTING FRACTIONS WITH LIKE DENOMINATORS
Whenever you subtract fractions with like denominators, you subtract the numerators to create the answer numerator, use the same denominators as the answer denominator. In other words, do not change the denominator for your answer.
DON'T FORGET TO CHANGE YOUR ANSWER IN LOWEST TERM!
Here are some few examples to help you.
5/6 - 1/6 = 4/6 or 2 /3
Show with picture or model.
3/4 - 1/4 = 2/4 or 1/2
1/3 - 1/3 = 0/3 or 0
7/10 - 3/10 = 4/10 or 2/5
1 - 1/9 = 8/9
To subtract a whole number to a fraction, we already know that the denominator has to be the same. In this case, the fraction's denominator in the left side is 9. We also know that any number that have the same numerator and denominator is equal to one. So the fraction will look like this:
9/9 - 1/9 = 8/9. (SIMPLE)
