Answer 1

a. 3/4 + 5/6 + 7/12 = 9/12 + 10/12 + 7/12= 26/12= 2 i 4/12= 2 i 1/3

b. 25/36 - 5/9 + 1/2= 25/36 - 20/36 + 18/36 = 5/36 + 18/36= 23/36

c. 1/3 + 2/5 + 9/10 = 10/30 + 12/30 + 27/30= 49/30 = 1 i 19/30

d. 4/15 - 1/6 + 4/5 = 8/30 + 5/30 + 24/30 = 37/30 = 1 i 7/30

Answer 2

a)  3/4 + 5/6 + 7/12 = 9/12 + 10/12 + 7/12 = 26/12 = 2 1/6

b) 25/36 - 5/9 + 1/2 = 25/36 - 20/36 + 18/36 = 5/36 + 18/36 = 23/36

c) 1/3 + 2/5 + 9/10 = 10/30 + 12/30 + 27/30 = 49/30 = 1 19/30

d) 4/15 - 1/6 + 4/5 = 24/90 - 15/90 + 72/90 = 9/90 + 72/90 = 81/90 = 9/10
