Question

The length of Giselle's arm is 27 inches. The length of her lower arm is 17 inches. About what percent of Giselle's arm is her lower arm?

Answer 1

About `67%`

Explanation:

The word 'about' suggests that just a quick estimate is required, rather an accurate answer.

Round `27 and 17` to `30 and 20` respectively.

What percentage is `20` out of `30`?

`20/30 = 2/3`

`2/3` as a percentage is `66 2/3%`

Her lower arm is aboyt `67%` of the length of her arm.
