Answer 1

Răspuns:

1. a=305,7-105,27=200,43

b=19,2-17,02+137,34= 2,18+137,34=139,52

a+b=200,43+139,52=339,95

2. 107,5-87,557=19,943

19,943+17,85=37, 793

3. a=3,125+15+82,3-17,32=

18,125+82,3=100,425-17,32= 83,105

b=13,7-1,05+21,31= 12,65+21,31= 33,96

a-b=83,105-33,96=49,145

4. a) 24,43-x=8,938

x=24,43-8,938

x=15,482

b) 7,28+x=132,57

x=132,57-7,28

x=125,29

c) x-37,5=132,04

x=132,04+37,5

x=169,54

d) x+4=27,5

x=27,5-4

x=23,5
