Question

A class has 6 boys and 15 girls. What is the ratio of boys to girls

Answer 1

$the \ ratio \ is : \\ \\ boys \ to \ girls = 6:15= 2:5$

Answer 2

we know that

Ratio is the quantitative relation between two numbers

so

Let

x-------> number of boys in the class

y-------> number of girls in the class

$ratio=\frac{x}{y}$

in this problem we have

$x=6\ boys\\y=15\ girls$

Find the ratio

substitute the values in the formula

$ratio=\frac{6}{15}$

Divide by $3$ both numerator and denominator

$ratio=\frac{2}{5}$

therefore

the answer is

the ratio of boys to girls is $\frac{2}{5}$
