Answer:

<h3 /><h3>7 boys and 21 girls in group.</h3>

Step-by-step explanation:

<h2>Given:</h2>

<h2>Solution:</h2>

Assume that all numbers of children is X.

Then, x:3x will be ratio.

<h3>Equation:-</h3>

➡ X + 3x = 28

➡ ️4x = 28

$\implies X = \cancel\dfrac{28}{4}^{ \bf \: 7}$

Boys = x = 7

Girls = 3x = 3 × 7 = 21

<h3>Hence, Total number of boys is 7 and </h3><h3>girls is 21.</h3>
