Question

Can I please get some help on these

Answer 1

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
