Answer:

18 gallons of paint could paint 10 classrooms.

Step-by-step explanation:

Given that the school bought 18 gallons of paint, and that each classroom requires 1 4/5 of paint to be painted, to determine how many classrooms can be painted with that amount of paint, the following calculation must be performed:

4/5 = 0.8

1 + 0.8 = 1.8

18 / 1.8 = 10

Therefore, 18 gallons of paint could paint 10 classrooms.

dimulka [17.4K]

Answer:

441 miles

Step-by-step explanation:

Rick traveled \frac{2}{3} of the way from his parents' house to his college dorm. He has driven 294 miles.

This means that

\dfrac{2}{3} \text{ of the way is } 294 \text{ miles}

Then

\dfrac{1}{3} \text{ of the way is } 294\div 2=147 \text{ miles}

and

\dfrac{3}{3} \text{ of the way is } 294+147=441 \text{ miles}
