Answer 2

8% of the children in the class are girls who wear glasses.

Step-by-step explanation:

Let the total number of students in a class = 100

40% of students are girls.

Number of girls in a class = $\frac{40}{100}\times 100 = 40$

20% of the girls wear glasses.

Number of girls wear glasses = $\frac{20}{100}\times 40 =8$

Percentage of the children in the class are girls who wear glasses = $\frac{8}{100}$ = 8%

Hence, 8% of the children in the class are girls who wear glasses.
