Question

Find the unknown value 16 is 40% of ???

Answer 1

let's say "x", therefore, "x" is the 100% then, and 16 is the 40% of it.


`\bf \begin{array}{ccll} amount&\%\\ \text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\ x&100\\ 16&40 \end{array}\implies \cfrac{x}{16}=\cfrac{100}{40}\implies x=\cfrac{16\cdot 100}{40}`
