1/10 + 1/5 = 1/10 + 2/10 = 3/10 = 0.3

4/3+5/6 = 8/6 + 5/6 = 13/6 = 2.16

7/3 + 7/9 = 21/9 + 7/9 = 28/9 = 3.1

2/7 + 5/14 = 4/14 + 5/14 = 9/14 = 0.64

3/20+7/5 = 3/20+ 28/20 = 31/20 = 1.55

4/3+5/18= 24/18 + 5/18 = 29/18 = 1.61

 

7/2-3/4 = 14/4-3/4 = 11/4 = 2.75

9/5-7/10 = 18/10-7/10=11/10=1.1

4/3-11/12 = 16/12-11/12= 5/12=0.41

25/14-10/7= 25/14-20/14=5/14=0.35

10/5-7/20= 40/20-7/20 = 33/20 = 1.65

5/3-5/18= 30/18-5/18= 25/18 = 1.38
