Part of a Whole Amount

Tyler ran 9 laps, which was 75% of his total run. How many laps was Tyler's run?

The 75% goes in the percent section.

The 9 laps is NOT the whole run, so it goes in the IS or PART section.

We are trying to find how many laps he should run...so the WHOLE!

Part of a Whole Amount

Tyler ran 9 laps, which was 75% of his total run. How many laps was Tyler's run?

Now multiply the 9 and 100 since they are diagonal from each other.

9 x 100 = 900

Then divide bly the 75 since it is alone.

900 / 75 = 12

His total run should be 12 laps!
