In Anna's grade, there are 50 students. Currently, 90% of them are enrolled in health. How many students are enrolled in health?

45

Step-by-step explanation:

50/10=5

5x9=45

45 of the students are enrolled in Health class.

Step-by-step explanation:

Here, it's simple: a percentage is a fraction of 100. But what's 100 ÷ 2? Surprise! It's 50! We could multiply 50 by .9 to find our answer, but here, we could also just divide 90 by 2 to get 90 ÷ 2 = 45

And there we go. 45 students in Anna's grade take health.

Hope this helps you understand! Have a great day!
