If 3/10 of a number is 15, how much is 6 times that number?

2. ## Re: Maths

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

3/10x15/1

4. ## Re: Maths

Let $x$ 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:

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

Now, we may solve this for $x$.
