Question

6500 is 7/10 of a number what is the number

Answer 1

Given the expression

6500 is 7/10 of a number, let the number be k

The expression is

`(7)/(10)\text{ of k}=6500`

Solve for k by crossmultiplying

`\begin{gathered} (7)/(10)\text{ of k}=6500 \\ (7)/(10)* k=6500 \\ (7k)/(10)=6500 \\ \text{Crossmultiply} \\ 7k=6500*10 \\ 7k=65000 \\ \text{Divide both sides by 7} \\ (7k)/(7)=(65000)/(7) \\ k=9285(5)/(7) \end{gathered}`

Hence, the number, k, is

`9285(5)/(7)`
