Question

40 is 50% of what number

Answer 1

If 40 represents 50%, to find which number represents 100%, we can use the next proportion

`(40)/(x)=\frac{50\text{ \%}}{100\text{ \%}}`

Solving for x,

`\begin{gathered} 40\cdot100=50\cdot x \\ (4000)/(50)=x \\ 80=x \end{gathered}`

Then, 40 is 50% of 80
