Answers
Step-by-step explanation:
Divisibility Test for 2: The last digit is 0, 2, 4, 6, or 8.
Divisibility Test for 3: The sum of the digits is divisible by 3.
The Rule for 4 : If the last two digits of a whole number are divisible by 4, then the entire number is divisible by 4.
Divisibility Test for 5: The last digit is 0 or 5.
A number is divisible by 6, if it is divisible by both 2 and 3.
Divisibility Test for 7: Cross off last digit, double it and subtract. Repeat if you want. If new number is divisible by 7, the original number is divisible by 7.
The Rule for 8: If the last three digits of a whole number are divisible by 8, then the entire number is divisible by 8.
The rule for divisibility by 9 is similar to divisibility rule for 3. That is, if the sum of digits of the number is divisible by 9, then the number itself is divisible by 9.
A number is divisible by 10 if it ends in a zero.
Divisibility Test for 11: For a 3-digit number, sum of the outside digits minus the middle digit must be 0 or 11.
