Question

107. 6 is 75% of what
number?

Answer 1

the number is really "x", which oddly enough is the 100%, but we also know that 15% of that is 107.6.

`\begin{array}{ccll} Amount&\%\\ \cline{1-2} x & 100\\ 107.6& 75 \end{array} \implies \cfrac{x}{107.6}~~=~~\cfrac{100}{75} \implies\cfrac{x}{107.6} ~~=~~ \cfrac{4}{3} \\\\\\ 3x=430.4\implies x=\cfrac{430.4}{3}\implies x=\cfrac{2152}{15}\implies x=143(7)/(15)\implies x=143.4\overline{66}`
