• Is divisible by 5 is it ends in 5 or 0
• Is divisible by 10 is it ends in 0
• Today we will learn the rules for divisibility by 3 and 9.
There are similarities in rules for 3 & 9
• To find out is something is divisible by 9, add the digits.
• 8217
• 18 is divisible by 9, therefore 8217 is divisible by 9.
• To find out if something is divisible by 3 , add the digits.
