Question

There are $1500$ students in a school$,$ out of which $600$ are girls$.$ What is the ratio of number of boys to the number of girls$?$

Answer 1

Step $1:$ To find the ratio of the number of boys to the number of girls

Given the Total number of students $=1500$

Number of girls $=600$

Number of boys $=1500-600$

$=900$

Step $2:$ Now find the ratio of the number of boys to girls

Required ratio $=900:600$

Step $3:$ Convert ratio into a fraction and write it into the simplest form

$900:600$ can be written as

$=\frac{900}{600}$

$=\frac{9}{6},$ divide the numerator and denominator by $3$

$=\frac{3}{2}$

Hence, the ratio of the number of boys to the number of girls is $3:2$
