four and sixteen16 - 4 = 1216 + 4 = 20 then 20 / 2 = 10Half of 12 is 6, therefore the two numbers 10 - 6 = 4 and 10 + 6 = 16 will have a mean of 10 and a range of 12.Further numbers can be added between 4 and 16 as long as their mean is still 10, eg the data sets:{4, 16}{4, 10, 16}{4, 8, 12, 16}{4, 8, 10, 12, 16}{4, 7, 9, 14, 16}all have a mean of 10 and a range of 12. There is an infinity of such sets.
16 rounded to the nearest 10 is 20.

16:20 = 8:10 = 4:5
mean(18, 23, 39, 10, 22, 17, 16, 15) = (18 + 23 + 39 + 10 + 22 + 17 + 16 + 15) ÷ 8 = 160 ÷ 8 = 20
16/20 = 8/10 = 4/5
16/20 + 6/20 = 11/10
20
The geometric mean of 10 and 20 is 14.1421356237
If you mean: 20 - 16 + 8 x 2 then it is 20
16 is 8/10 of 20.
16/20 = 8/10 = 4/5
