Because think of like fractions as the same things.. you can subtract halves from halves for example, but what does it mean to take away a half from a third?
By converting them into like fractions, we can add or subtract them easily.

Subtracting fractions is similar to adding fractions. If the fractions have the same denominator, you subtract the numerators. If the fractions have different denominators, you have to convert to a common denominator first.Subtracting fractions is similar to adding fractions.

What did you learn from adding and subtracting fractions?
I learned to always change the denominators before adding or subtracting the numerators. You must always have a common denominator before adding or subtracting.
