Answer 2

a) 12/7
b)MMC(9,3)=9
41/9-2/3=41-6/9= 35/9

c)11/2+2/3
mmc(2,3)=6
3.11+2.2/6= 33+4/6= 37/6

d)MMC(3,4)=12
4.5-3.3/12= 20-9/12= 11/12

e)MMC(5,10)=10
10.5+2.3+8/10
50+6+8/10=
64/10= 32/5

f)MMC(4,6)=12
12.10-7.3-2.5/12
120-21-10/12
120-31/12
89/12

g)1/4+20/3+5/6
MMC(4,3,6)= 12
3.1+4.20+2.5/12
3+80+10/12
93/12= 31/4

h)27/5-1/3+1/2
MMC(5,3,2)= 30
6.27-10.1+15.1/30
162-10+15/30= 162+5/30
167/30
