Answer 2

Answer:

The ratio of the number of Girls to the number of boys in the class is 3:2.

Step-by-step explanation:

Given:-

• Total number of Girls out of the students in the class = 18
• Girls in Percentage = 60 %

To Find:-

• The Ratio of number of girls to the number of boys in the class.

Solution:-

Let the Total number of Students be 'x'.

60% of x is girls .

Therefore, 60% of x = 18

$\frac{60}{100} \times x = 18$

$= > x = \frac{18 \times 100}{60} = 30$

Number of Students = 30.

So, the number of boys = 30 - 18 = 12

Hence, ratio of the number of girls to the number of boys is 18:12 or

$\frac{18}{12} = \frac{3}{2}$

3/2 is written as 3:2.
