Question

Is 46,386 divisible by both 3 and 9? Why or why not?

Answer 1

Every number divisible by 9 is divisible by 3. A number is divisible by 9, if the sum is a multiple of 9 or if the sum of its digits is divisible by 9.

In this case:

`\begin{gathered} 46,386 \\ 4+6+3+8+6=27 \\ 27\text{ is divisible by 9} \end{gathered}`

Then, 46,386 is divisible by 9 and by 3 because every number divisible by 9 is divisible by 3.
