Answer:
11. 10/9 = 80/72
12. 8/12 = 72/108
13. 22/99 = 2/9
14 4 41/123 = 4 1/3
15. 84/840 = 1/10
16. 6/14 vs 3/7 (cross multiply numerators and denominators)
42 vs 42
Therefore 6/14 = 3/7
17. 2/3 vs 5/7 (cross multiply numerators and denominators)
14 vs 15
Therefore 2/3 < 5/7
18. 1/5, 1/2, 1/4 (Change to decimals then compare)
.20 .50 .25
Therefore increasing order is 1/5, 1/4, 1/2
19. 5/7, 5/6, 7/9 (Change to decimals then compare)
.71 .83 .77
Therefore increasing order is 5/7, 7/9, 5/6

We want to solve
y'' + 3y' = 0
Solve the indicial equation.
m² + 3m = 0
m(m + 3) = 0
m = 0 or m = -3
