Question

Jerry mixed 7/8 cup olive juice with 7/8 cup pickle juice. He drank 7/8 of a cup and threw out the rest. How much did he trow out?

Answer 1

7/8 of a cup. If you add 1+1 and then take away 1, you still have 1.

Answer 2

So first, do the addition.
$\frac{7}{8} + \frac{7}{8} = \frac{14}{8}$
Then, subtract $\frac{14}{8} - \frac{7}{8} = \frac{7}{8}$

He threw out $\frac{7}{8}$ of a cup.
