Q3. In a class of 40, number of girls is 10, what is the ratio of the number of boys to the number of girls?​

Answer 1

Answer:

is question ka answer 4:1 hoga

Answer 2

Let "n" represent the number of boys

Formula:

$10+n=40$

Solve:

$10+n=40\\10-10+n=40-10\\n=30$

The ratio is:

30:10

we need to simplify it, find the GCF of 30 and 10, the answer is 10 so we divide 10 to both.

30 / 10 = 3

10 / 10 = 1

Answer:

3:1
