Question 161990
I would first convert all terms into fractions

7/12,4/3,25/12,17/6

The difference between 7/12 and 4/3

We first need to find the common denominator:12

7/12 
(4/3)(4/4)=16/12   16/12-7/12=9/12

The difference between 4/3 and 25/12  the common denominator is also 12

25/12-16/12=9/12

The difference between 25/12 and 17/6 The common denomiator is 12


34/12 -25/12=9/12

So 9/12 is added to a previous term 

34/12+9/12=43/12=3_7/12

43/12+9/12=52/12=13/3 or 4_1/3

52/12+9/12=61/12=5_1/12

3_7/12,4_1/3,5_1/12
