Question

The number of measles cases increased 33.7% to 220 cases this year. What was the number of cases prior to the increase?

Answer 1

Hi there!

Multiply 33.7 with 0.01...

`33.7`·
`0.01=0.337`

Then multiply 0.337 with the cases which is 220.

`0.337`·
`220=74.14`

This means that 33.7% of 22 is 74.14 and this also means that the increased cases this year is 74.14.
