How do you subtract a fraction?

1 answer:

6 0

Answer: It's easy.

Step-by-step explanation: When the denominators of the two fractions you're subtracting are the same, in your answer they should also stay the same. Just subtract the numerators [top numbers].

When the denominators are not the same, if you can simplify the denominators so they can be the same number, do it.

For example: 2/4 - 1/2

Change 2/4 to 1/2 so that the equation turns into 1/2 - 1/2.
