12/5 = x/6
Cross multiply; that is, multiply 12 times 6 (=72) and 5 times x (=5x). Then 5x = 72, and I know you can solve the rest.
Since cross-multiplication is really just a shortcut for the steps you would take to solve any equation, here is the solution without the gimmick:
12/5 = x/6
Multiply both sides by 30, the lowest common denominator, to elimate the fractions.
72 = 5x
Divide both sides by 5 to solve for x.

cross multiply
12*6=72
5*x=5x
5x=72... divide both sides by 5 to get x by itself
x=14.4

Cross multiplication.
12/5 = x/6
12x6 = 5x
72 = 5x
x = 72/5
x = 14.4

12/5 = x / 6
multiply the numerator on each side by the denominator on the opposite side & you get
72 = 5x
divide both sides by 5 & you get
x = 72/5
