# Josie had 1 gallon of ice cream. She used 3/10 gallon to make a chocolate milkshake and 3/10 gallon to make a vanilla milkshake. How much ice cream is left?

$\frac{2}{5}$ gallon.

#### Explanation:

$\frac{3}{10}$ gallon - chocolate shake

$\frac{3}{10}$ gallon - vanilla shake

So

$\frac{3}{10} + \frac{3}{10} = \frac{6}{10}$

Now

$\text{1 gallon" \ - 6/10 \ "gallon}$

$= \frac{10}{10} \setminus \text{gallon" - 6/10 \ "gallon" = 4/10 \ "gallon}$

Simplified: $\frac{2}{5}$ gallon
