Question
: In a class of 30 students, 18 are girls. What percentage of the class are boys?
Solution
Step 1: First, find out the number of boys in the class. Since there are 30 students in total and 18 of them are girls, subtract 18 from 30 to get the number of boys.
30 - 18 = 12 boys
Step 2: Now, to find out the percentage of boys in the class, divide the number of boys by the total number of students and then multiply the result by 100.
(12 boys / 30 students) * 100 = 40%
So, 40% of the class are boys.
