Question

How do you solve `8/15=x/120`?

Answer 1

`x=64`

Explanation:

Right now, `x` is being divided by `120`, so we can multiply both sides by `120` to isolate it. We get

`64=x` or in the more traditional way,

`x=64`

Another approach is to think: How did we get from `15` to `120`? One way would be to multiply by `8`.

We know these fractions are equal, so we can multiply the top by `8` to get

`x=64`

Hope this helps!
