You paint 1/2 wall in 1/4 hour. At that rate, how long will it take you to paint one wall?

How do you figure out these problems, I seem to have a hard time.

What do you multiply by 1/2 to get 1?

Multiply 1/4 by the same number to find how long it will take to paint one wall.
Thank you Ms. Sue, got it correct.
You're welcome. :-)
