Answer 1

a) 1,2 + 5/6= 1 1/5+ 5/6 =1 6/30 + 25/30 =1 31/30 =2 1/30

b)4,8 - 1 1/3=4 4/5 - 1 1/3 = 4 12/5- 1 5/15= 3 7/15

c)33,3 + 1\3 - 1,25= 33 3/10 + 1/3 -1 1/4= 33 18/60 + 20/60 - 1 15/60= 33 38/60 - 1 15/60= 32 23/60

d) 2,25 - 1 1\3 - 1,5 = 2 ¼ - 1 1/3 – 1 ½ = 2 3/12 – 1 4/12 – 1 6/12 = -7/12
