40 because 3+6+12 = 21 and 8+11+21 =40
8/3 = 2 2/3 and -11/3 = -3 2/3
so the middle line is 0 and each big line is 1.
Put the first dot on 2 2/3 or right before the 3rd big line.
Put the second dot on -3 2/3 or the line right after the 4th big line going back from 0

Step-by-step explanation:
V would be 72
you need to multiple 3, 4, and 6.
doing it in separate steps could be easier
3 x 4 is 12. then 12 x 6 is 72
or if u have a calculator, just punch 3 x 4 x 6 which should give you 72
The decimal is actually .825 you move the decimal 2 places. So the fraction is 33/40
