Question

suppose a charity received a donation of $22.8 million. if this represents 58% of the charity's donated fund, what is the total amount of its donated funds?

Answer 1

the total amount is "x", so, if 22.8 is 58%, "x" is the 100%,


`\bf \begin{array}{ccllll} amount&\%\\ \text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\ 22.8&58\\ x&100 \end{array}\implies \cfrac{22.8}{x}=\cfrac{58}{100}\implies \cfrac{22.8\cdot 100}{58}=x`
