To determine how many cups are in four gallons, we start with the fact that there are 16 cups in one gallon. Therefore, to find the total number of cups in four gallons, we need to multiply the number of cups per gallon by the number of gallons:
\[ 4 \text{ gallons} \times 16 \text{ cups/gallon} = 64 \text{ cups} \]
Now, let's evaluate the provided expressions to see which ones accurately reflect this calculation:
- 16 ÷ 4 - This does not pertain to calculating cups in gallons. (Not applicable)
- 16 ÷ 4 - Same as above. (Not applicable)
- 16 × 4 - This would yield 64 cups, which is correct. (Applies)
- 4 × 16 - This is also equal to 64 cups, which is correct. (Applies)
- 4 × 16 - Same as above (Applies)
- 16 + 16 + 16 + 16 - This equals 64 cups, which is also correct. (Applies)
- 16 + 16 + 16 + 16 - Same as above. (Applies)
- 16 + 4 + 16 + 4 - This does not give us the correct value; it totals to 40. (Not applicable)
The three correct expressions that describe how many cups are in four gallons are:
- 16 × 4
- 4 × 16
- 16 + 16 + 16 + 16
You can select those three.
