A)

adadad : ad = 10101

B) adcadc : adc= 1001

Răspuns:

adadad : ad =

Descompunem in baza zece

(100000a + 10000d + 1000a + 100d + 10a + d) : (10a + d) =

[10a × (1000 + 100 + 1) + d × (10000 + 100 + 1)] : (10a + d) =

(10a × 10101 + 10101d) : (10a + d) =

10101 × (10a + d) : (10a + d) =

10101 × 1 = 10101

adcadc : adc =

(1000 × adc + adc) : adc =

adc × (1000 + 1) : adc =

adc × 1001 : adc = 1001
