Sticky Note
Of the class of 40 students, 20% are girls. how many boys are in the class?
  1. 26
  2. 28
  3. 30
  4. 32
Explanation

If 20% of the students are girls, then the remaining percentage (100% - 20% = 80%) represents the boys.

So, in a class of 40 students:

80% of 40 = (80/100) * 40 = 0.8 * 40 = 32

Therefore, there are 32 boys in the class.
