Question

The are 16 cups in a gallon. Which expressions describe how many cups are in four gallons? Check THREE that apply.

A. 16 + 4
B. 16 divided by 4
C. 4 x 16
D. 16 x 4
E. 16 + 16 + 16 + 16

Answer 1

To determine how many cups are in four gallons, we can use the fact that there are 16 cups in one gallon. Therefore, for four gallons, we calculate:

\[ \text{Cups in 4 gallons} = 4 \times 16 \]

Now let's evaluate the given options:

A. \(16 + 4\) -> This does not correctly represent the calculation for cups in four gallons.
B. \(16 \div 4\) -> This does not represent the calculation for cups in four gallons.
C. \(4 \times 16\) -> This correctly represents the calculation for cups in four gallons.
D. \(16 \times 4\) -> This is mathematically equivalent to \(4 \times 16\) and also correctly represents the calculation for cups in four gallons.
E. \(16 + 16 + 16 + 16\) -> This adds 16 four times, which totals 64 cups, thus it also correctly represents the calculation for cups in four gallons.

The correct answers are **C, D, and E**.
