Question

afla care este diferenta dintre a si b stiind ca: a=73-27:(37-28)+2. b =(5+5*9):5*9

Answer 1

a=73-27:(37-28)+2
a=73-27:9+2
a=73-3+2
a=70+2
a=72

b =(5+5*9):5*9
b =(5+45):45
b=50:45
b=10/9

a-b=72-10/9=(72x9-10)/9=(648-10)/9=638/9=70,89

Answer 2

a=73-27:(37-28)+2
a=73-27:9+2
a=73-3+2
a=73-5
a=68

b=(5+5•9):5•9
b=(5+45):5•9
b=50:5•9
b=50:45
b=1,(1)

A-B=68-1,(1)=66,(8)
