Question

One-half​ of the students in a school are girls, 3/5 of these girls
are studying in lower classes. What fraction of girls are studying in
lower classes?

Answer 1

Answer:

3/10 girls study in the lower classes

Step-by-step explanation:

Girls studying in a school = 1/2 of students

Girls studying in lower classes = 3/5 of 1/2 girls

                                                   = 3/5 *1/2

                                                  = 3/10

Answer 2

Given:

The total number of females in a school is one-half of the total number of students.

females studying in lower classes are 3/5 of the total girls.

To find:

To obtain the fraction of females studying in lower classes.

Solution:

Let us take the total number of students as X.

The total number of females in a school = 1/2 of X = (1/2)X

The total number of females studying in lower classes = (3/5) of (½)X

= (3/5) × (½)X

= (3/10) X

Fraction of females studying in lower classes = Total females in lower classes/ Total students in the school

= (3/10) X / X

= 3/10

Hence, The fraction of females studying in lower classes is 3/10.
