Question

In a class of $44$ students, $\frac{5}{11}$of them are girls. How many boys are there in the class $?$

Answer 1

Total number of students $=44$

Total number of girls

$=\frac{5}{11}$ of $44$

$$\begin{gathered} =\frac{5}{11}\times 44 \\ =20 \end{gathered}$$

Total number of boys$=$ total students in the class $-$ total number of girls

$$\begin{gathered} =44-20 \\ =24 \end{gathered}$$

Hence, total number of boys $=24$
