Answer 1

a)=29/4-5/2-23/6+7/3= 87/12- 30/12 - 46/12 + 28/12 = 57/12 - 46/12 - +28/12 = 11/12 + 28/12 = 39/12

b)4 1/5 - 2 3/4 + 1 1/8 - 2 7/10 =21/5-11/4+9/8-27/10= 336/80 - 220/80 + 90/80 - 216/80= -10/80

c) 3 7/12 - 1 3/5 - 1 11/20 + 1 5/6 =43/12 - 8/5 - 31/20 + 11/5= 215/60 - 48/60 - 93/60 + 66/60= 140/60

d)8 5/36 - 3 7/9 - 2 1/8 - 1 7/8 =293/36 - 34/9 - 17/8 - 15/8= 586/72 - 272/72
