The number two to 55 is the same as the number six is to 165. This reduces down to the decimal .036 (with "36" repeating) or approximately 3.63 percent.
To find this relationship, simply cross multiply using the fractions 2/55 x 6/n. Therefore, 2n is equal to the product of 6 x 55, 330. Since 330 divided by 2 is 165, 2 is to 55 as 6 is to 165. To confirm this finding by calculator, 2/55 must equal the same result as 6/165, which holds true. This same formula is used to solve a proportion whenever three of the four terms are known.
