Question

Find the percentage form of.....
1) 2:8
2) 4/5
3) 1.25
​

Answer 1

➤ Answer :-

${\tt \longrightarrow 2:8 = \dfrac{2}{8}}$

Percentage form :-

${\tt \longrightarrow \dfrac{2}{8} \times 100}$

${\tt \longrightarrow \cancel \dfrac{2}{8} \times 100 = \boxed{\tt \dfrac{1}{4} \times 100}}$

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

${\tt \longrightarrow \cancel \dfrac{100}{4} = \boxed{\tt 25 \bf\%}}$

${\tt \longrightarrow \dfrac{4}{5}}$

Percentage form :-

${\tt \longrightarrow \dfrac{4}{5} \times 100}$

${\tt \longrightarrow \dfrac{4}{ \cancel{5}} \times \cancel{100} = \boxed{\tt \dfrac{4}{1} \times 20}}$

${\tt \longrightarrow \dfrac{4 \times 20}{1} = \dfrac{80}{1}}$

${\tt \longrightarrow \cancel \dfrac{80}{1} = \boxed{\tt 80 \bf\%}}$

━━━━━━━━━━━━━━━━━━━━━━━━━━

${\tt \longrightarrow 1.25 = \dfrac{125}{100}}$

Percentage form :-

${\tt \longrightarrow \dfrac{125}{100} \times 100}$

${\tt \longrightarrow \dfrac{125}{ \cancel{100}} \times \cancel{100} = \boxed{ \tt\dfrac{125 \times 1}{1}}}$

${\tt \longrightarrow \cancel\dfrac{125}{1} = \boxed{\tt 125 \bf\%}}$
