Answer 1

3/4 + 1/3 = 9/12 + 4/12 = 1 1/12

 

2/3-1/5 = 10/15 - 3/15 = 7/15

 

3/8 + 1/2 = 3/8 + 4/8 = 7/8

 

7/9 - 2/3 = 7/9 - 6/9 = 1/9

 

1 1/6 + 2 4/9 = 3 + (3/18 + 8/18) = 3 + 11/18

 

13/4 - 11/6 = 39/12 - 22/12 = 16/12 = 1 1/3

Answer 2

3/4+1/3=9/12 +4/12= 13/12 czyli 1 i 1/2

2/3-1/5= 10/15 -3/15 = 7/15

3/8+1/2=3/8+4/8= 7/8

7/9-2/3= 7/9 -6/9=1/9

1 i 1/6+2 i 4/9=7/6 +22/9 =63/54 +132/54=195/54

3 i 1/4-1i 5/6=13/4 - 11/6 = 78/24 - 44/24 = 34/24=17/12
