How do You Subtract Fractions?

You subtract fractions by arranging the fractions so that they have the same denominator (bottom number) and then subtracting the numerators (top number) as usual. The answer will be the value of the subtracted numerators above the common denominator. For example: 5/2 – 2/4 becomes 10/4 – 2/4 which is equal to 8/4 or 2.
