Yes, they are related.

yes, but they are not twins, ones 13 and ones 15

12 + 13 + 15 = 4012 + 13 + 15 = 4012 + 13 + 15 = 4012 + 13 + 15 = 40
12 + 13 + 15 = 4012 + 13 + 15 = 4012 + 13 + 15 = 4012 + 13 + 15 = 40
13 over 15 = 13 ÷ 15 = 0.866667
13% of 15 is: 1.95
13/15 = 13 ÷ 15 = 0.8667
First put them in numerical order,12, 13, 13, 15, 15, 18.since there is an even set of numbers the median is the mean of the two middle numbers12, 13, 13, 15, 15, 18.(13+15)/2=14
percent changes from 15 to 13
x/13 = 15 x = 15(13) x = 195
The factors of 13 are 1 and 13. (It is prime)The factors of 15 are 1, 3, 5, and 15.
