How can we write "3/10 of a number is 15" as an equation?

3/10x15/1

Let $\displaystyle x$ represent the number, since we don't know what it is. We are told that if we multiply this number by 3/10, the result is 15:

$\displaystyle \frac{3}{10}\cdot x=15$

Now, we may solve this for $\displaystyle x$. - Oct 2nd 2012, 09:13 AMSpixol123Re: Maths
