a - b = 110
a : b = 4 rest 5
a = 4×b+5 (conform teoremei impartirii cu rest)
a |____|____|____|____|+5
b |____|
4 segmente egale + 5 - 1 segment egal = 3 segmente egale + 5 = 110
110 - 5 = 105
105 : 3 = 35 (un segment egal)
a = 4×35+5 = 140+5 = 145
b = 35
Verificare:
145 - 35 = 110
145 : 35 = 4 rest 5
