Question

It rained 4.2 inches in 12 hours. At this rate,
how much will it rain in 27 hours?

Answer 1

9.45 inches

Explanation:

We should make a proportion for this one.

4.2/12=x/27

Now we cross multiply.

12x=113.4

Now we divide both sides by 12.

x=113.4/12

We solve 113.4/12.

x=9.45 inches
