Question

1. a mechanic uses 5/8 quart of oil per engine. if he services 16 engines, how much oil is used in total? (2 points) * 8 quarts 9 quarts 10 quarts 12 quarts

Explanation:

Step1: Identify the operation

We need to multiply the oil - used per engine by the number of engines. The oil used per engine is $\frac{5}{8}$ quart and the number of engines is 16. So the operation is $\frac{5}{8}\times16$.

Step2: Perform the multiplication

$\frac{5}{8}\times16=\frac{5\times16}{8}$. Since $16\div8 = 2$, then $5\times2=10$.

Answer:

10 quarts
