$\frac{19}{24}$ $19/24$ of a cup of mix is left.

Explanation:

Add $\frac{3}{4} and \frac{2}{3}$ $3/4 and 2/3$ of a cup together.
Then subtract $\frac{5}{8}$ $5/8$ of a cup that is eaten.

We can write the required expression as:

$\frac{3}{4} + \frac{2}{3} - \frac{5}{8} \leftarrow$ $3/4 +2/3-5/8" "larr$ find a common denominator.

The LCD is 24. Find the equivalent fractions

$\frac{18 + 16 - 15}{24}$ $(18+16-15)/24$

$= \frac{19}{24}$ $=19/24$
