Answer 2

7 boys and 21 girls in group.

Explanation:

Given:

• There are 28 children.
• the ratio of boys to girls is 1:3.

To find:

• Numbers of boys and girls

Solution:

Assume that all numbers of children is X.

Then, x:3x will be ratio.

Equation:-

➡ X + 3x = 28

➡ ️4x = 28

`\implies X = \cancel(28)/(4)^( \bf \: 7)`

Then x = 7

Boys = x = 7

Girls = 3x = 3 × 7 = 21

Hence, Total number of boys is 7 and

girls is 21.
