The pattern goes like this 12 = 100% , 12 /12 = 1, 100 /1 = 100% , 12 / 6 = 2 , 100 / 2 = 50% , 12 / 3 = 4, 100 / 4 = 25% , and to answer the questions 1 month out of 12... 12 / 1 = 12 , 100 / 12 = 8.33 . To verify this, 8.33 * 12 = 99.96 , since 6 > 5 , you can estimate the 9 to the next digit which is .9 + .1 making 1.0 , then 99.00 + 1.0 = 100%.

8.34 x 12 = 100.08 (close enough)
