Question

a:7=12rest5
136:b=6rest4

Answer 1

a=7x12+5=> a= 84+5=> a=89

b=136:6+4=> b=(136-4):6=> b=132:6=> b=22

:)

Answer 2

a : 7 = 12 rest 5

a = 12 × 7 + 5 → teorema impartirii cu rest

a = 84 + 5

a = 89 → deimpartitul

Verific: 89 : 7 = 12 rest 5

136 : b = 6 rest 4

b = ( 136 - 4 ) : 6 → teorema impartirii cu rest

b = 132 : 6

b = 22 → impartitorul

Verific: 136 : 22 = 6 rest 4
