c) 2,75 + 2/7
d) 0,125 - 1/9
e) 3 1/3 - 3,3

Answer 1

a) 3,6 +2/3 = 3 i 38/30
b) 4 1/8 - 1,11 = 3 i 12/800
c) 2,75 + 2/7 = 2 i 725/ 700
d) 0,125 - 1/9 = 1025/ 900
e) 3 1/3 - 3,3 = 1/30

Answer 2

a 36/10 +2/3= 78/30+20/30= 3 i 8/30

b 33/8 -111/100= 4125/1000 - 1110/1000= 3015/1000= 3 i 15/1000

c 1925/700+200/700= 2125/700= 3 i 25/700

d 1125/9000- 1000/9000= 125/9000

e 33/10- 10/3= 99/30-100/30= -1/30
