I would just set it up as a proportion and cross multiply. 68/2=110/? or 2/68=?/110
what is the ? for
The ? is the answer. You solve for that.
how like what do i do
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.
