10 is 5% of what number


Sagot :

We can use proportion to get the result
10 ----------- 5%
x ------------- 100%
Crossmultiply proportion

5*x=10*100
5x=1000     /:5 divide both sides by 5
x=1000:5
x=200 - its the answer


[tex]p\%=\frac{p}{100}\\\\5\%=\frac{5}{100}=0.05\\\\x-the\ number\\\\5\%\ of\ the\ number\ (x)\Rightarrow 0.05x\\\\The\ equation:\\\\0.05x=10\ \ \ \ \ |divide\ both\ sides\ by\ 0.05\\\\x=\frac{10}{0.05}\\\\x=\frac{1000}{5}\\\\\boxed{x=200}\leftarrow ANSWER[/tex]
