Question

Suppose that 11 inches of wire costs 66 cents.

At the same rate, how many inches of wire can be bought for 42 cents?

Answer 1

7 inches of wire

Explanation:

We Know

11 inches of wire = $0.66

1 inches of wire = 0.66 / 11 = $0.06

At the same rate, how many inches of wire can be bought for 42 cents?

We Take

0.42 / 0.06 = 7 inches of wire

So, 7 inches of wire can be bought for 42 cents.
