Final answer:
The proportion 16 miles/18 quarts = 24 miles/27 quarts is true.
Step-by-step explanation:
To determine whether the proportion 16 miles/18 quarts = 24 miles/27 quarts is true or false, we need to check if the two ratios are equal. We can do this by cross-multiplying:
16 miles * 27 quarts = 24 miles * 18 quarts
432 miles/quarts = 432 miles/quarts
Since both sides of the equation are equal, the proportion is true.
