Question

Suppose that 11 inches of wire costs 33 cents.

At the same rate, how many inches of wire can be bought for 12 cents?

Answer 1

4 inches of wire.

Explanation:

• 11 Inches = 33 cents

∴ 1 cent can buy 11/33 = 1/3 inches

∴ 12 cents can buy 12 × 1/3 = 4 inches

Answer 2

36

you can divide 33/11 to get the amount of money for 1 inch which is 3 cents

then multiply 12 by that 3 to get 36
