Answer 1

7(1/10)+1(3/10)=8(4/10)=8,4

3(2/7)+3/7=3(5/7)

5(4/9)+3(2/9)=8(6/9)=8(2/3)

 

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

 

25/7+31/7=56/7=8

31/29+11/29=42/29=1(20/29)

 

79/13+97/13=176/13=13(7/13)

13/9+17/9=30/9=3(3/9)=3(1/3)

 

 21/31+32/31=53/31=1(22/31)

65/53+95/53=160/53=3(1/53)

21/10-3/10=18/10=1,8

45/22-3/22=42/22=1(20/22)

73/25-13/25=60/25=2(10/25)=2,4

 

 

 

 

 

 

 

 

Answer 2

7 1/10+1 3/10=8 4/10=8 2/5

3 2/7+3/7= 6 5/7

5 4/9+3 2/9=8 6/9=8 2/3

7/11+11 2/11=11 9/11

25/7+31/7= 56/7=8

31/29+11/29=42/29=1 13/29

79/13+97/13= 176/13=13 7/13

13/9+17/9=30/9=3 3/9=3 1/3

21/31+32/31=53/21=2 11/21

65/53+95/53=160/53=3 1/53

21/10-3/10= 18/10= 1 8/10=1 4/5

45/22-3/22=42/22=1 20/22=1 10/11

73/25-13/25=60/25=2 10/25=2 2/5

 

Answer 3

7 + 1/10 + 1 + 3/10 = 8 + 4/10 = 8 + 2/5 = 8 2/5 3 + 2/7 + 3/7 = 3 5/7 + 3/7 = 4 1/7 5 + 4/9 + 3 + 2/9 = 8 + 6/9 = 8 2/3 7/11 + 11 + 2/11 = 11 7/11 + 2/11 = 12 25/7 + 31/7 = 56/7 = 8 31/29 + 11/29 = 42/29 79/13 + 97/13 = 176/13 = 13 5/13 13/9 + 17/9 = 30/9 = 3 1/3 21/31 + 32/31 = 53/31 65/53 + 95/53 = 160/53 21/10 - 3/10 = 18/10 = 9/5 45/22 - 3/22 = 42/22 = 21/11 73/25 - 13/25 = 60/25 = 12/5
