Which car got more miles to 1 gallon?

If each of these tables represents ratios, then ANY pair of numbers in a row is that ratio.

So, Car A got 10 ÷ 0.3125 = 32 miles to 1 gallon. And Car B got 5 ÷ 1/6 = 30 miles to 1 gallon.

Car A has a greater ratio of miles to gallons than Car B, so it got more miles to 1 gallon.

Knowing your operations—addition, subtraction, multiplication, and division—is so important, even to help you learn algebra! Division is one of the trickiest, so it's important to practice until you can think of division facts in your head.

For example, what is 72 ÷ 7? Well, 10 × 7 = 70, so 72 ÷ 7 = 10 with 2 left over.

Think of division expressions and try to get the quotient in your head. Then check your guess on the interactive tool at the right. Practice makes perfect!
