Answer 2

A)
9/15 + 4/15 =13/15

b)
7/11 + 2/11 =9/11

c)
4 i 3/8 + 2 i 4/8 = 6 i 7/8

d)
3/9 + 7/9 =

= 10/9=

= 1 i 1/9


e)
3 i 2/3 + 2/3 =

= 3 i 4/3 =

= 4 i 1/3



f)
4 i 3/5 + 2/5 =

= 4 i 5/5=

= 5 


g)
4 i 6/7 + 2 i 1/7 =

= 6 i 7/7 =

= 7


h)
3 i 5/10 + 4 i 9/10 =

= 7 i 14/10 =

= 8 i 4/10 =

= 8 i 2/5



i)
2 i 4/6 + 7 i 5/6 = 

= 9 i 9/6 =

= 10 i 3/6=

= 10 i 1/2
