Question

Using divisibility tests, determine which of the following numbers are divisible by $10$:
(a) $54450$ (b) $10800$ (c) $7138965$ (d) $7016930$ (e) $10101010$

Answer 1

A number is $divisible$ by $10$ if the last digit is $0$
So, $54450,10800,7016930,10101010$ are divisible by $10$ and $7138965$ is not divisible by $10$.
