My son is stuck on this maths homework question and I do not know how to do this. The question says: "there are $682$ girls in a crowd of $1000$. What percent is this". Use no calculator.
We have done $\dfrac{682}{1000}$ and simplified to $\dfrac{341}{500}$ but now am stuck...how do I get this into a percentage?
you need multiply by 100, i.e.
$$\frac{682}{1000}\times100=68,2\%$$
