Question

pleasegive me all with method​

Answer 1

➤ Answer :-

Fractional form :-

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

Percentage form :-

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

${\tt \longrightarrow \dfrac{4 \times 100}{5} = \dfrac{400}{5}}$

${\tt \longrightarrow \cancel\dfrac{400}{5} = \boxed{\tt 80 \bf\%}}$

━━━━━━━━━━━━━━━━━━━━━

Decimal form :-

${\tt \longrightarrow 0.04 = \dfrac{4}{100}}$

Percentage form :-

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

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

${\tt \longrightarrow \cancel \dfrac{4}{1} = \boxed{\tt 4 \bf\%}}$

━━━━━━━━━━━━━━━━━━━━━

Percentage form :-

${\tt \longrightarrow 40 \bf\%}$

Decimal form :-

${\tt \longrightarrow 40 \bf\% = \tt \dfrac{40}{100}}$

${\tt \longrightarrow \cancel\dfrac{40}{100} = \boxed{\tt 0.4}}$

━━━━━━━━━━━━━━━━━━━━━

${\tt \longrightarrow 15 \bf\% \sf \: \: of \tt \: \: 240}$

${\tt \longrightarrow \dfrac{15}{100} \times 240}$

${\tt \longrightarrow \dfrac{15}{ \cancel{100}} \times \cancel{240} = \dfrac{15}{5} \times 12}$

$\tt \longrightarrow \cancel \dfrac{15}{5} \times 12 = \boxed{\tt 3 \times 12}$

$\tt \longrightarrow 36$

More to know................

• Percentage is written by the symbol of %.
• Percentage is used all over the world for many purposes. It is mostly used in calculating the marks of the students in schools and collages. The percentage can also be converted to fraction, decimal and ratio formats.
• To convert fraction to percentage, we should multiply the given fraction with 100.
• To convert decimal to percentage, first we should convert it to fractional form and then multiply by 100.
• To convert the ratio to percentage, first we should convert it to fraction form and then multiply by 100.

Answer 2

$\huge\star\:\:{\orange{\underline{\blue{\mathbf{Solution}}}}}$

• Convert the given fraction into percentage
• $\sf\dfrac{4}{5}$

Fractional form that is given -

${\sf \implies \dfrac{4}{5}}$

Percentage form :-

• ${\sf \implies \dfrac{4}{5} \times 100}$

• ${\sf \implies \dfrac{4 \times 100}{5} = \dfrac{400}{5}}$

• ${\sf \cancel \dfrac{400}{5} = 80 \%}$

________________________________

• Convert the given decimal fraction into percentage
• 0.04

Decimal form that is given :-

• ${\sf \implies 0.04 = \dfrac{4}{100}}$

Percentage form that needs to be converted :-

• ${\sf \implies \dfrac{4}{100} \times 100}$

• ${\sf \dfrac{4}{ \cancel{100}} \times \cancel{100} = \dfrac{4 \times 1}{1}}$

• ${\sf \cancel \dfrac{4}{1} = 4 \% }$

________________________________

• Convert the given percentage into decimal fraction

Percentage form :-

• ${\sf \implies 40 \%}$

Decimal form :-

• ${\sf \implies 40 \% = \sf \dfrac{40}{100}}$

• ${\sf \cancel\dfrac{40}{100} = {\sf 0.4}}$

________________________________

• Convert 15% of 240

• ${\sf \implies 15 \% \sf \: \: of \sf \: \: 240}$

• ${\sf \implies \dfrac{15}{100} \times 240}$

• ${ \sf \implies \dfrac{15}{ \cancel{100}} \times \cancel{240} = \dfrac{15}{5} \times 12}$

• ${\sf \cancel \dfrac{15}{5} \times 12 = 3 \times 12}$

• ${\sf \implies 36}$
