The problem would be set up like this...

12 over x = 40 over 100

X represents the percentage we're trying to find, and the 100 below 40 percent represents 100 percent, which is constant among these types of problems.

Cross multiply...

40x = 12 * 100

40x = 1200

Divide both sides by 40.

x = 30.
