Question

The strength of the class is $65$, including $30$ girls. Find the ratio of the number of :
iii) the whole class to girls

Answer 1

Finding the ratio of the number of the whole class to girls :

Given,
$\text{Total strength of class}=65$
$\text{Number of girls}=30$
$\text{The ratio of total strength to girls}=\frac{\text{Total strength}}{\text{Number of girls}}=\frac{65}{30}$
Now, above ratio can be converted to its simplest form by dividing numerator and denominator by $5$, we get
$\frac{65÷5}{30÷5}=\frac{13}{6}=13:6$
Therefore, the ratio of total strength to girls is $13:6$.
