Răspuns:

Explicație pas cu pas:

3,5*10-27,3=35-27,3=7,7

4,3*5+2,5=21,5+2,5=24

13,2+5,4*8=13,2+43,2=56,4

4,53*100-2,7*23=453-62,1=390,9

20,47*5=102,35

57:2,5-0,31=22,8-0,31=22,49

a) 3,5*10-27,3=35-27,3

=7,7

b)4,3×5+2,5=21,5+2,5

=24

c)13,2+5,4*8=13,2+43,2

= 56,4

d)4,53*100-2,7*23=453-62,1

=390.9

e)la e cred ca ai gresit.

d)57:2,5-0,31=22,8-0,31

=22,49
