Question

A 6-inch candle burns down in 12 hours. After how many hours will it have burned
4 inches?

Answer 1

8 hours

Explanation:

Let's first find how many inches the candle would have burned in 1 hour.

6 in:12 hours

x: 1 hour

We can divide 12 by 12 to get 1. This means we need to divide 6 by 12 to get x

x=1/2 inches

1/2 inches:1 hour

4 inches: x hours

We divide 4 by 1/2 to get 8. 1/2*8=4. This means...

x=1 hour*8=8 hours
