Two-thirds of students in a class are girls. If one-half of the girls wear glasses, what fractional part of students are girls w

Fantom [35]

Let's assume the number of students in the class be x.

Given that, Two-thirds of students in a class are girls.

So, number of girls $=\frac{2}{3} x$

Now ne-half of the girls wear glasses. So, one-half of $\frac{2}{3} x$ is

= $\frac{1}{2} *\frac{2}{3} x$

= $\frac{1}{3} x$ Cancel out 2 from both numerator and denominator.

So, one third of the students are girls who wear glasses.

So, the correct choice is E.
