Explanation:

First Problem (Sue's Rice)

Step1: Multiply fraction by total cups

$\frac{4}{5} \times 3 = \frac{12}{5}$

Step2: Convert to mixed number (optional)

$\frac{12}{5} = 2\frac{2}{5}$

Step1: Recall fraction multiplication rule

$\frac{1}{5} \times 3 = \frac{3}{5}$

Step2: Match to division form

$\frac{3}{5} = 3 \div 5$

Answer:

$\frac{12}{5}$ or $2\frac{2}{5}$ cups
