Answer 1

A) 1,2 + 5/6 = 1 2/10 + 5/6 = 12/10 + 5/6 = 72/ 60 + 50/60 = 122/60  = 2 2/60 
b) 4,8 - 1 1/3 =48/10 - 4/3 = 144/30 - 40/30 = 104/30 = 3 14/30 = 3 7/15
c) 33,3+1/3-1,5=33 3/10+1/3-1 5/10=46/10+1/3-15/10=138/30+10/30-45/30=
=148/30-45/30=103/30=3 13/30
d) 2,25 - 1 1/3 1,5 = 2 25/100 - 1 1/3 - 1 5/10 = 225/100 - 4/3 - 16/10 = 675/300 - 400/300 - 480/300 = - 205/300
