Divisibility Rules for 5 and 10

This lesson covers quick methods to determine if a whole number is divisible by 5 or 10. For divisibility by 5, a number must end in 0 or 5. For divisibility by 10, the number must end in 0. Examples are provided to illustrate these rules, such as 325 and 110 being divisible by 5, and 110 being divisible by 10, while 203 and 101 are not. The lesson concludes with a recap of these divisibility checks.
