Question

There are 30 girls and 20 boys in a class. In the class, 23

of the girls are wearing blue shirts and 75% of the boys are wearing green shirts. There are how many more girls wearing blue shirts than there are boys wearing green shirts?

Answer 1

Answer: 8

Explanation:

Calculations:

20 ⋅ .75 = 15 (boys wearing green shirts)

23 - 15 = 8

To find the number of boys wearing green shirts you need to divide the percentage (75%) by 100 to get a decimal (.75). Multiplying the decimal by the number of boys in class gives you the number of boys wearing green shirts. Then all that's left is to subtract.
