Question

The ratio of numbers of girls and boys participating in sports of a school is 4:5. If the
number of girls is 212, determine the number of boys participating in the sports.

Answer 1

let the number of girls 4x

but number of girls =212

so,

4x=212

x=212/4

x=53........(i)

number of boys =5x

put the value of x

=5*53=265

answer=265

Answer 2

✬ Boys = 265 ✬

Step-by-step explanation:

Given:

• Ratio of girls and boys participating in school is 4 : 5.
• Number of girls is 212.

To Find:

• What is the number of boys participating in sports ?

Solution: Let x be the common in given ratios. Therefore,

➙ Number of girls = 4x

➙ Number of boys = 5x

A/q

• Number of girls = 212

$\implies{\rm }$ 4x = 212

$\implies{\rm }$ x = 212/4

$\implies{\rm }$ x = 53

Hence,

➢ Number of girls = 4x = 4(53) = 212

➢ Number of boys = 5x = 5(53) = 265
