Answer 1

0,75+4/5=0,75+0,8=1,55

5/6+0,3=0,83+0,3=1,13

0,25+3/7=0,25+0,43=0,68

4 i 5/8+0,6=32,62+0,6=33,22

0,15+7 i 1/3=0,15+7,3=7,45

3/4+4,56=0,75+4,56=5,31

10 i 1/2+2,875=10,5+2,875=13,375

1,02+3 i 9/50=1,02+150,18=151,2

2 i 5/9+1,4=2,55+1,4=3,95

Answer 2

a) o,75 + 4/5= 0,75 + 8/10= 0,75 + 0,8= 1,55
b) 5/6+ 0,3= 5/6 + 3/10= 25/30 + 9/30= 34/30= 1 i 4/30= 1 i 2/15
c) 0,25 + 3/7= 1/4 + 3/7= 7/28 + 12/28 = 19/28
d) 4 i 5/8 + 0,6= 4 i 625/1000 + 0,6= 4,625 + 0,6= 5,225
e) 0,15 + 7 i 1/3 = 15/100 + 7 i 1/3 = 3/20 + 7 i 1/3 = 9/60 + 7 i 20/60= 7 i 29/60
f) 3/4 + 4,56= 0,75 + 4,56= 5,31
g) 10 i 1/2 + 2,875= 10,5 + 2,875= 13,375
h)1,02 + 3 i 9/50= 1 i 2/100 + 3 i 9/50 = 1 i 2/100 + 3 i 18/100 = 4 i 20/100 = 4,2
i) 2 i 5/9 + 1,4= 2 i 5/9 + 1 i 2/5= 2 i 20/45 + 1 i 18/45 = 3 i 38/45
