Answer 1

1. a) 2,3+3,1=5,4

b) 6,9+4,7=11,6

c) 5,6+2,8=8,4

d) 1,18+3,56= 4,74

e) 4,39+ 2,807=7,197

f)13,085+26,77= 39,855

2. a) 12,9-8,7=4,2

b) 7,31-2,8=4,51

c)6,02-5,7= 0,32

d) 13,42-6,87= 6,55

e) 18,009-11,42=6,589

f) 35- 18,76= 16,24

3. 4,15+21,3-9,28= 23,45-9,28 =16,17

11,1-7,25+2,7= 3,85+2,7= 6,55

4,3+3,01-7,3= 7,31-7,3= 0,01

11-2,54-3,825= 8,46- 3,825=4,605

0,3+3+0,33= 3,3+0,33=3,63

12,08-7,56+0,03= 4,52+0,03=4,55

4. 3,8- 1,2 = 2,6 ( 6:5=1,2)

8,4-0,16= 8,24 ( 4:25=0,16)
