Question

Paige was given this problem on her math homework and she came up with this answer

Her math teacher counted this problem wrong and Paige does not know why.

Using complete sentences, explain what Paige did wrong and how to correctly solve the problem.

Answer 1

The answer is incorrect, because she flipped 3/4 to 4/3. When you use 'Keep Change Flip', you keep the first fraction, change the / sign to a * sign, and flip the second fraction (or change it to it's reciprocal). 3/4 / 2/5 = 3/4 * 5/2 = 15/8 = 1 7/8.
