Q. Without dividing, determine if

55

,

230

is divisible by

5

and explain how you know.

\newline

55,230 \square \text { divisible by } 5

Check Last Digit: To determine if a number is divisible by $5$ , we only need to look at the last digit of the number. If the last digit is either $0$ or $5$ , then the number is divisible by $5$ .
Last Digit of $55,230$ : The last digit of $55,230$ is $0$ . Since $0$ is one of the digits that makes a number divisible by $5$ , we can conclude that $55,230$ is divisible by $5$ without performing any division.
