Question

During a given month, there was a total of 23.6 inches of rain. this was 250% of the average rainfall for that month. What is the average rainfall for that month?

Answer 1

9.44 inches

Explanation:

In order to find the average rainfall, setting up a proportion, or equivalent ratios, would be the easiest way to find the measurement. Given that 23.6 inches represents 250% of the average:

`(23.6)/(250)=(x)/(100)`, where 'x' represents the average rainfall

cross-multiply: 250x = (23.6)(100) or 250x = 2360

divide: 250x/250 = 2360/250

x = 9.44 inches
