Answer:
7 boys and 21 girls in group.
Step-by-step 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
[tex] \implies X = \cancel\dfrac{28}{4}^{ \bf \: 7} [/tex]
Then x = 7
Boys = x = 7
Girls = 3x = 3 × 7 = 21
Hence, Total number of boys is 7 and
girls is 21.
