Answer:
it rained 0.58 inches in April.
Explanation:
To find how much it rained in April, we have to subtract 0.39 from 0.97.
0.97 - 0.39 = 0.58
We know to do this because the question says that it rained 0.39 inches LESS than in March. This means we need to subtract 0.39 inches from how many inches it rained in March.
