Okay, here's a hint: you can undo the division here by using multiplication.

So what you're going to want to do here is get rid of the 5 and the 3. You can do that by multiplying the whole whole equation by 5 (to get rid of the 5 part) and then when you're done with that, multiply the whole equation by 3. That's a whole lotta' work, so what you can do instead is find a number that both 5 and 3 go into. Then, multiply the whole equation by that number. Can you think of a good number to use?

You completely jogged my memory Ty. And regarding the other method i'd say 15.

14. melbel Group Title

I would try 15 instead of 3 and 5 (but you got it) since you would have to multiply the entire equation by 3 and then by 5. It's a lot to write down. But yeah, you got it. :)
