Suma a trei nr. este 897. Daca din fiecare nr. se scade acelasi numar se obtine respectiv restul: 25 , 61 , 124 . Care sunt numeralele??? VAROGG AM NEVOIEE!!!

Answer 1

a+b+c=897
a-?=25⇒a=?+25
b-?=61⇒b=?+61
c-?=124⇒c=?+124
a /............./__+25__./
b /............/______+61_____/                            ⇔897
c /............/___________+124___/
3 parti+25+61+124=897
3 parti+210=897
3 parti=897-210
3 parti=687
1 parte=687:3
1 parte=229
?=229 (este nr. care se scade)
a=229+25=254
b=229+61=290
c=229+124=353
a+b+c=254+290+353=897

Answer 2

a.!--------!_+25_!
b.!--------!_+61__!
c.!--------!_+124__!
a+b+c=897
897-(25+61+124)=897-210=687
687:3=229-nr care se scade din a ,b si c.
a=229+25=>a=245
b=229+61=>b=290
c=229+124=>c=353
P:254+290+354=897
