Answer 1

To find out how many cups are in four gallons, we can use the following expressions:

1. **4 × 16**: This directly calculates the number of cups in four gallons, as there are 16 cups in one gallon.

2. **16 + 16 + 16 + 16**: This adds the number of cups for each of the four gallons, which also gives the correct total.

3. **16 × 4**: This is another way to multiply the number of cups in one gallon by four gallons, yielding the same result as the first expression.

The three expressions that correctly describe how many cups are in four gallons are:

- **4 × 16**
- **16 + 16 + 16 + 16**
- **16 × 4**

The incorrect options are:

- **16 ÷ 4** (this calculates the number of cups in one fourth of a gallon)
- **16 + 4** (this is not relevant to the calculation of cups in four gallons)

So the correct answers are: **4 × 16**, **16 + 16 + 16 + 16**, and **16 × 4**.
