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
13/15 = 13 ÷ 15 = 0.8667
13% of 15 is: 1.95
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
The ratio of 15 to 13 can be expressed as 15:13. This means for every 15 units of one quantity, there are 13 units of another. It can also be simplified to a decimal, which is approximately 1.15 when divided (15 ÷ 13).
x/13 = 15 x = 15(13) x = 195
