Question

ratio of boys and girls in a school is 5:3 If there are 300boys , find the number of girls.​

Answer 1

Answer:

180 girls

Step-by-step explanation:

let the number of boys be 5x and girls be 3x

no of boys is 300

so 5x=300

x=60

substitute x in 3x

3×60

so the number of girls is 180

Answer 2

The ratio of boys and girls in a school ⇒ $5:3$

Number of boys ⇒ $5x$

Number of girls ⇒ $3x$

Now we know the value of boys in a school. The value of boys is ⇒ $300$

Now we have to solve the equation ⇒

$5x=300$

$x=\frac{300}{5}$

$x=60$

Now let's find the number of girls keeping $x=60$.

So the number of girls is ⇒

$3x = 3\times 60$

$3x = 180$

∴ The number of girls in the school is 180.
