If the digit sum of a number adds up to 9 then it is divisible by 9.
The divisibility rules of 4 and 9 are combined to make the divisibility rule of 36.
it is divisible by 3 and 9
It is 3 6 9
Yes. It is the divisibility rule for 9.
Its digital sum is 9 so it is divisible by 9
the divisibility rule for 2 is: The number is even;the last digit ends with a 2,4,6,8,10, etc.The divisibility rule fir 3 is: The sum of the number is divisible by 3The divisibility rule for 4 is: The last two digits are divisible by 4The divisibility rule for 5 is: The number ends with a 5 or 0The divisibility rule for 6 is: The sum CAN be divisible by 2 and or 3The divisibility rule for 9 is: The sum of the number is divisible by 9The divisibility rule for 10 is : The number ends with a 0
It is even and the sum of its digits is divisible by 9.
There is no easy rule for divisibility by 34.
By tautology. If it did not work, it would not be a divisibility rule!
why does the divisibility rule work for 4
9 because the digits of 36 add up to 9
Its digits add up to 9 so therefore it is divisible by 9
