Question

Create a proportion using the form %/100 = is/of to represent the following word problem. Sixteen is 15% of what number? 16/100 = x/1515/100 = x/16 16/100 = 15/x 15/100 = 16/x

Answer 1

Consider a% of b is x and it is written as,

`(a)/(100)* b=x`

Given that 15% of x =16 , to find the value of x,

`\begin{gathered} (15)/(100)* x=16 \\ (15)/(100)=(16)/(x) \end{gathered}`

Hence the correct expression for 15% of x =16 is 15/100=16/x

Answer: option 4) 15/100=16/x is correct.
