Answer 1

2/5+0,3+(0,8-1/2)=2/5+3/10+0,8-1/2=7/10+8/10-1/2=7/10+4/5-1/2=3/2-1/2=1
(1:0,3-2 1/3)-5/6=(10/3-7/3)-5/6=1-5/6=1/6
3 1/3-1/3*0,6=10/3-1/3*6/10=10/3-1/3*3/5=10/3-1/5=47/15=3 2/15

Answer 2

4/10 + 3/10 + (8/10 - 5/10) = 7/10 + 3/10 = 10/10 = 1
(1:3/10 - 7/3) - 5/6 = (1*10/3 -7/3) - 5/6 = 1- 5/6 = 1/6
10/3 -1/3*6/10 = 10/3 - 1/5 = 30/15 - 3/15 = 27/15
