Question

4/5 + 1/10 4 3/4 + 2 2/3
1/6+2/3
8/9 - 1/3
1 3/10 - 1/5
2/3 +1/5
4/7 + 1/2
2 2/5 + 3 1/2

Answer 1

4/5 + 1/10 = 

= 8/10 + 1/10 =

= 9/10



4 i 3/4 + 2 i 2/3=

= 4 i 9/12 + 2 i 8/12=

= 6 i 17/12=

= 7 i 5/12



1/6+2/3=

= 1/6 + 4/6=

= 5/6



8/9 - 1/3=

= 8/9 - 3/9 =

= 5/9




1 i 3/10 - 1/5=

= 1 i 3/10 - 2/10 =

= 1 i 1/10




2/3 +1/5=

= 10/15 + 3/15=

= 13/15




4/7 + 1/2=

= 8/14 + 7/14=

= 15/14=

= 1 i 1/14




2 i 2/5 + 3 i 1/2=

= 2 i 4/10 + 3 i 5/10=

= 5 i 9/10

Answer 2

4/5 + 1/10 = 8/10+1/10=9/10 4 3/4 + 2 2/3= 4 9/12 + 2 8/12 = 617/12 = 7 5/121/6+2/3 = 1/6 + 4/6 = 5/6
8/9 - 1/3 = 8/9 - 3/9 = =5/9
1 3/10 - 1/5 =1 3/10 - 2/10 = 1 1/10
2/3 +1/5 = 10/15+3/15 = 13/15
4/7 + 1/2 = 8/14 + 7/14 = 15/14 = 1 1/14
2 2/5 + 3 1/2= 2 4/10 + 3 5/10 = 5 9/10
