Answer 1

1/7 + 5/14= 2/14 + 5/14= 7/14= 1/2
b) 3/4 + 5/12=9/12 + 5/12 = 14/12= 1 i 2/12= 1 i 1/6
c) 8/9 - 5/18= 16/18 - 5/18 = 11/18
d) 1/3 + 3/4=4/12 + 9/12= 13/12= 1 i 1/12
e) 3/5- 1/2= 6/10 - 5/10= 1/10
f) 1 i 1/2 - 1/3= 1 i 3/6 - 2/6= 1 i 1/6
g) 1 i 1/2 + 3/8= 1 i 4/8 + 3/8= 1 i 7/8
h) 1 i 1/3 - 2/9=1 i 3/9 - 2/9= 1 i 1/9
i) 2 i 3/5 - 7/10= 2 i 6/10 - 7/10= 1 i 16/10 - 7/10= 1 i 9/10
j) 5/6 - 1/4= 10/12 - 3/12= 7/12
k) 1 i 1/6 - 7/9= 1 i 3/18 - 14/18= 21/18- 14/18= 7/18
l) 2 i 3/8 - 1 i 5/6= 2 i 9/24 - 1 i 20/24=1 i 33/24 - 1 i 20/24= 13/24
