Answer 1

a)

8 1/7+7 8/9+2 2/18=8 1/7+7 8/9+2 1/9=8 1/7+9 9/9=8 1/7+10=18 1/7

b)

4 5/6+9 5/8+7 3/18=4 15/18+9 5/8+7 3/18=9 5/8+11 18/18=9 5/8+12=21 5/8

c)

11 5/8-5 35/56-3 5/9=11 5/8-5 5/8-3 5/9=6-3 5/9=2 4/9

d)

6 2/12-4 1/4+5 5/6=6 2/12-4 3/12+5 10/12=1 11/12+5 10/12=6 21/12=7 9/12=7 3/4

Answer 2

a) 8i1/7 +7i8/9 +2i2/18= 8i1/7 + 7i8/9 +2i1/9= 8i1/7 + 9i9/9 = 8i1/7 +10= 18i1/7

 

b) 4i5/6 +9i5/8 +7i3/18= 4i5/6 +9i5/8 +7i1/6= 11i6/6 + 9i5/8= 12 +9i5/8= 21i5/8

 

c) 11i5/8 -5i35/56 -3i5/9 = 11i5/8 -5i5/8 -3i5/9= 6 -3i5/9= 5i9/9 -3i5/9= 2i4/9

 

d) 6i2/12 - 4i1/4 +5i5/6= 6i1/6 -4i1/4 + 5i5/6= 11i6/6 -4i1/4 =12 -4i1/4= 11 i4/4 - 4i1/4= 7i3/4
