Question

Diferenta a doua nr este 45 .Afla cele doua nr stiind ca impartind nr mare la nr mic obtinem catul 5 restul 5

Answer 1

a-b=45
a:b=5 rest 5....=> a=b*5+5

b*5+5-b=45
5b+5-b=45
4b+5=45
4b=45-5
4b=40

b=40:4

b=10

a=10*5+5


a=50+5


a=55




55:10=5 rest 5

Answer 2

Notam nr cu a si b
a-b=45
a:b= 5 rest 5 => a=5×b+5
Inlocuim in scadere
5×b+5-b =45
4 ×b+5=45
b=40:4
b=10
a=50+5=55
