Answer 1

Răspuns:

A)

66,44:5,4=12,3

38.88:3,6=10,8

12,3-10,8=1,5

B)

7,14:0,42=17

1,748:0,04=43,7

17+43,7=60,7

C)

160,62:2,8=57,4

32,31:0,6=53,8

57,4-53,8=3,6

D)

400,4:0,28=1,43

83,2:0,52=160

1,43-160=-158,3

E)

24,7:10=2,47

2,848:16=0,1

2,4-0,1=2,3

F)

108,45:0,15=723

12,15:0,27=45

723-45=678
