I would just set it up as a proportion and cross multiply. 68/2=110/? or 2/68=?/110

68 = 110

---- ----

2 x

This is how to set up the proportion that zorro was talking about, although he did it incorrectly.

Cross multiply:

110 (2) = 220

68 (x) = 68x

Therefore:

220 = 68x

Solve for x by dividing by 68 on both sides.
