# Calculating percentage basics

I am new to this website, so please forgive my mistakes if there is any.

I'm not quite good standing with mathematics and I have trouble finding the solution for this problem:

60% of the number 50 equals 30. I know this from my own logic, but how would I solve the issue mathematically?

Thanks.

Hint: $60\%$ is the same as $\frac{60}{100}=\frac{6}{10}$.
So you just need to compute the product $$\frac{6}{10}\times 50.$$
If you want to compute how much $p\%$ is you compute as above but if you want to add $p\%$ to a number $x$, just compute the product $(100+p)/100\times x$ to obtain $x+p/100\times x$. – Sigur Feb 10 '13 at 10:56
