Question

$80\%$of what number is $6$$?$

Answer 1

Finding the number by using percentage:

Let the number be $x$

$80\%$of $x$ $=$ $6$

$\frac{80}{100}\times x=6$ ( $80\%$ can be written as$\frac{80}{100}$)m

$80\times x=6\times 100$( bring $100$from left side to right side and while doing so division gets changed to Multiplication )

$x=\frac{600}{80}$( bring $80$from left side to right side and while doing so multiplication gets changed to division )

$x=\frac{600}{80}$( simplify $\frac{600}{80}$by dividing by a factor $80$ in numerator and denominator separately )

$x=7.5$

Hence, $80\%$of $7.5$is $6$.
