I am sorry. The answer is 6 because 21/3=7, meaning that the numbers were multiplied by 3. So you would multiply 2 by 3, making 6. And that is how I recieved my answer.

ok!

Answer 15

Here's an example

5/6 = x/720

We cross multiply

5 * 720 = 6 * x

and we need to get x all by itself so we divide 6 on both sides and we get

x = 5*720/6
x = 600

Hopefully that helps you understand even more :)
