Sometimes a percent is less than 1%.
A group of 600 students takes a test. Only
3 students get a perfect score. What percent
of the group gets a perfect score?

To find the percent, rename as an equivalent percent.

0.00. 5 0.5%

So 0.5% of the group gets a perfect score.

You can use the meaning of percent to rename a
decimal or fraction as an equivalent percent less than 1%.
