Answer 2

➤ Given :-

Total children in school :- 500

Part of children playing :- ${\tt\dfrac{4}{5}}$

Part of children reading :- ${\tt\dfrac{1}{10}}$

➤ To Find :-

Number of children playing and reading.............

➤ Solution :-

Number of children playing :-

$\tt \longrightarrow \dfrac{4}{5} \sf \: \: of \tt \: \: 500$

${\tt \longrightarrow \dfrac{4}{ \cancel{5}} \times \cancel{500} = \dfrac{4}{1} \times 100}$

${\tt \longrightarrow \dfrac{4 \times 100}{1} = \dfrac{400}{1}}$

${\tt \longrightarrow \cancel \dfrac{400}{1} = \boxed{\tt 400 \sf \: \: children}}$

Number of children reading :-

${\tt \longrightarrow \dfrac{1}{10} \sf \: \: of \tt \: \: 500}$

${{\tt \longrightarrow \dfrac{1}{ \cancel{10}} \times \cancel{500} = \dfrac{1}{1} \times 50}}$

${\tt \longrightarrow \dfrac{1 \times 50}{1} = \dfrac{50}{1}}$

${\tt \longrightarrow \cancel \dfrac{50}{1} = \boxed{\tt 50 \sf \: \: students}}$

$\Huge\therefore$ 400 children are playing and 50 children are reading.
