Answer 2

28/21 = 4/3

83/27 is already in its simplest form.

72/90 can be simplified by dividing both the numerator and denominator by their greatest common factor (GCF), which is 18. This gives us:

72/90 = 4/5

18/4 can be simplified by dividing both the numerator and denominator by their GCF, which is 2. This gives us:

18/4 = 9/2

5/75 can be simplified by dividing both the numerator and denominator by their GCF, which is 5. This gives us:

5/75 = 1/15

25/175 can be simplified by dividing both the numerator and denominator by their GCF, which is 25. This gives us:

25/175 = 1/7

12/24 can be simplified by dividing both the numerator and denominator by their GCF, which is 12. This gives us:

12/24 = 1/2

18/108 can be simplified by dividing both the numerator and denominator by their GCF, which is 18. This gives us:

18/108 = 1/6

210/1540 can be simplified by dividing both the numerator and denominator by their GCF, which is 70. This gives us:

210/1540 = 3/22

33/42 can be simplified by dividing both the numerator and denominator by their GCF, which is 3. This gives us:

33/42 = 11/14

23/46 can be simplified by dividing both the numerator and denominator by their GCF, which is 23. This gives us:

23/46 = 1/2

52/26 can be simplified by dividing both the numerator and denominator by their GCF, which is 26. This gives us:

52/26 = 2/1 = 2
