A circle graph has a 90° slice for walk, what percent walk

Step by step

The question

Question: a circle graph has a 90° slice for walk: what percent walk?

Here is the slice.

90° of the 360° circle.

1 Angle over 360

The slice is 90 out of 360 degrees.

90 and 360 can both be divided by 90: 1/4.

Careful!

Degrees are out of 360, not out of 100.

2 As a percent

Percent means out of 100.

1/4 times 100% is 25%.

3 Check

Let's check: 25% of 360 degrees is 90°, the slice.

So the answer is right!

Let's look back.

First: angle over 360.

Then: as a percent.

Last: check.
