Answer 2

$\huge \red{ \boxed{ \bf\color{green}{ \frac{32}{5} } = \color{orange}{6 \frac{2}{5} }}}$

Step-by-step explanation:

To find the number whose -

$\bf12 \frac{1}{2} \% \: is \: 80$

_____________________

SOLUTION :-

let the number as x,

So,

$\bf12 \frac{1}{2} \%of \: x = 80 \\ \\ \bf = > \frac{(2 \times 12) + 1}{2} \times x = 80 \\ \\ \bf = > \frac{24 + 1}{2} \times x = 80 \\ \\ \bf = > \frac{25}{2} \times x = 80 \\ \\ \bf = > 25 \times x = 80 \times 2 \\ \\ \bf = > 25 \times x = 160 \\ \\ \bf = > x = \frac{160}{25} \\ \\ \bf \large= > \red{x} = \purple{ \frac{32}{5} } = \color{yellow}{6 \frac{2}{5} }$

Hence,

The number is 32/5 = 6 2/5
