Question

Subtract. Write your answer in simplest for. 2/3 - 3/8

Answer 1

First we need common denominators so we can multiply 2/3 by 8 and 3/8 by 3. Now we would have 16/24 - 9/24 which would be 7/24. 7/24 cannot be simplified because 7 cannot be multiplied by anything to get 24. The answer would be 7/24

Answer 2

The lowest common denominator of 3 and 8 is 24, thus you must multiply 2/3 by 8/8 and 3/8 by 3/3. This is 16/24-9/24, which is equal to 7/24.
