Answer 1

A. 1,2 + 5/6 = 6/5 + 5/6 = 36/30 + 25/30 = 61/30 = 2 1/30
B. 4,8 - 1 1/3 = 4  8/10 - 1 1/3 = 4 24/30 - 1 10/30 = 3 14/30 = 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 1/4 - 1 1/3 - 1 1/2 = 2 3/12 - 1 4/12 - 1 6/12 = - 7/12
