Question

8 1/2% of what is 20?

Answer 1

then we need to find a original number multiplied by the percent and what solution is 20

we wirte a relation

$\begin{gathered} 8\frac{1}{2}\longrightarrow20 \\ \\ 100\longrightarrow x \end{gathered}$

because 8 1/2% is equivalent to 20 and we need to find the 100%

now to find x(missing value) we multiply the diagonal numbers (100 and 20) and divide between 8 1/2

$x=\frac{100\times20}{8\frac{1}{2}}$

to multiply we transform the mixed number to decimal

$8\frac{1}{2}=8.5$$x=\frac{100\times20}{8.5}$

and solve

$x=235.3$

Finally

8 1/2% of 235.3 is 20
