We can say that 600 represents 100% and 12 represents x %. Using the proportion: 600 : 12 = 100 : x. That can also be written as: 600/12 =100/x. Then we will multiply across the known corners and then divide by the third number. 600 x = 12 * 100 600 x = 1,200 x = 1,200 : 600, x = 2. Answer: 12 is 2% of 600.
