min= 12 max=21 median=17 mode=17 mean=191

Sum = 85 Number = 5 So mean = 85/5 = 17

(21+15+19+28+10+17+9+15+26+14+10+18+24+12+16) / 15 = 16.93 recurring (that is, 16.93333...)

13 + 21 - 7 + 12 = 15

The Least Common Multiple (LCM) for 21 15 12 29 is 12,180.

18/21 x 15 is 12 6/7

It is: 420

-12 + 18 - (-15) = -12 + 18 +15 = 21

you add all of the numbers in the group together and then divide the number you get by how many numbers are in the group EX: your group is 21, 32, 12, 15. you add 21+32+12+15= 80. then you divide 80 by 4 because you have four numbers in your group. so your mean is 20!

If you mean 15/21 then lowest terms is 5/7
