A maintenance worker is painting transport vehicles. It takes $\frac{3}{5}$ of a gallon of paint to cover one vehicle. If the worker needs to paint $15$ identical vehicles, what is the total number of gallons of paint required?

Cevap: 9 gallons

The correct answer is found by taking the required amount of paint per vehicle (

\frac{3}{5}

) and multiplying it by the total number of vehicles (

15

). The calculation is

15 \times \frac{3}{5} = \frac{15 \times 3}{5} = \frac{45}{5} = 9

gallons.
