\[f = \frac{ ab }{ b+1 }\]

Answer 2

find a...
hmm. oh i see it! it's in the numerator of your fraction!

Answer 3

just kidding. we want to isolate the a on the right side. first get rid of that b + 1. how might we do that?

Answer 4

-b -1

Answer 5

f = ab/b+1
fb + f= ab
fb+f/b =a

Answer 6

if something is in the denominator and you want to get rid of it...multiply both sides by that denominator you want to get rid of. multiply both sides by b + 1.

Answer 7

multiply?!?!
