Question

15 is 20% of what numberOA 3O B. 60O C 75O D. 300

Answer 1

c)75

Step-by-step explanation

to figure out this, we can use a rule of three

so,

let x represents the unknown value(

`\begin{gathered} if \\ 15\Rightarrow20\text{ \%} \\ \text{then} \\ x\Rightarrow100\text{ \%} \end{gathered}`

make the proportion and solve for x

`\begin{gathered} (15)/(20)=(x)/(100) \\ \text{cross multiply} \\ 15\cdot100=20\cdot x \\ 1500=20x \\ (1500)/(20)=x \\ 75=x \end{gathered}`

so, the answer is

C)75

I hope this helps you
