Question

Identify the percent amount and base in this problem.150 is 25 percent of what number.

Answer 1

let's say that number is "x", so that is then the 100%.

if 150 is 25%, what is "x"?

`\bf \begin{array}{ccll} amount&\%\\ \cline{1-2} x&100\\ 150&25 \end{array}\implies \cfrac{x}{150}=\cfrac{100}{25}\implies \cfrac{x}{150}=4\implies x=600`
