First you find the median, the middle term (if there are an even number of terms it is the average of the middle two terms.) Since you have 21 terms, odd, you just use the middle term, in this case 8. The first quartile works the same way, but just on the left half between the start and the median...so the first quartile is 6.

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
