Test the divisibility of 5629003 by 11.

1.	Test the divisibility of 5629003 by 11.
Answer» According to the rule of divisibility by 11 = 3 × 1 + 0 × (- 1) + 0 × (1) + 9 (- 1) + 2 (1) + 6 × (- 1) + 5(1) = 3 + 0 + 0 – 9 + 2 – 6 + 5 = 10 – 15 = – 5 That is not divisible by 11 So, the number 5629003 is not divisible by 11

Answer»

According to the rule of divisibility by 11

= 3 × 1 + 0 × (- 1) + 0 × (1) + 9 (- 1) + 2 (1) + 6 × (- 1) + 5(1)

= 3 + 0 + 0 – 9 + 2 – 6 + 5

= 10 – 15

= – 5

That is not divisible by 11

So, the number 5629003 is not divisible by 11
