Put them in ascending order. Subtract the smallest value from the largest.
17
It is 15, the number halfway between the two middle numbers.
mean(18, 23, 39, 10, 22, 17, 16, 15) = (18 + 23 + 39 + 10 + 22 + 17 + 16 + 15) ÷ 8 = 160 ÷ 8 = 20
16/25 is greater than 12/23
22.5
17
To get the (mean) average, add them up and divide by 3 [since there are 3 numbers]: 12 + 16 + 23 = 51, and 51 ÷ 3 = 17.
