Question

example of divisibility by 11 7 digit number​

Answer 1

Step-by-step explanation:

Students may enjoy thinking about how this divisibility test is related to the Fun Fact Divisibility by Seven. 2728 = 2 * 1000 + 7 * 100 + 2 * 10 + 8, so its remainder when divided by 11 is just 2(-1) + 7(1) + 2(-1) + 8(1), the alternating sum of the digits.
