Question

Kyle often pretends to take showers. He was told 330 times to take a shower, but only took one 264 times. What percentage of the time did he pretend to take a shower?

Answer 1

Kyle pretended to take a shower for `20%` of the times he was asked.

Explanation:

The times Kyle pretended to take a shower amount to `(330-264)`, that is `66`.

To determine what percentage `66` is of `330`, we write the equation:

`330xxx/100=66`

Multiply both sides by `100/330`.

`x=66xx100/330`

`x=66xx(10cancel(0))/(33cancel(0))`

`x=2cancel66xx10/cancel33`

`x=2xx10`

`x=20`
