# Thread: Make C the subject: F=(9/5)C + 32.

1. ## Make C the subject: F=(9/5)C + 32.

I don't remember what to do with the fraction in this

I am trying to find out what C equals.

F=(9/5)C + 32.

So I subtracted 32 from both sides so now its

F - 32 = (9/5)C

But I dont remember what to do to get rid of the 9/5...

2. ## Re: Help with a problem

multiply both sides by 5/9
