Question

Find the percent of increase from 33 songs to 63 songs. Round to the nearest tenth of a percent if necessary.

Answer 1

`90.9`%

Explanation:

First, note that
`63/33=21/11= 1~10/11`.

Recall that
`1/11=0.090909090909...`. This means that
`10/11=1-1/11=1-0.0909090909...=0.909090909090...`

This means that the percentage increase was
`90.9`%
