There are different rules for different number
2: ends in 2,4,6,8,0
3: digits add up to multiple of 3
4: last two digits are divisible by 4
5: ends in 5,0
6: follows the rules of both 2 and 3
9: digits add up to a multiple of 9
10: ends in 0

How can we Describe a rule for deciding if a number is divisible by three consider numbers greater than 1000?
The rule for deciding if a number is divisible by 3 is to add up the digits of the number. If that total is a multiple of 3, the original number is as well. This applies to numbers of any length.
What is a divisibility rule that you can use to decide whether a number is divisible by both 5 and 10?
Use the divisibility rule for 10. If the number is divisible by 10, then it is obviously also divisible by 5.
Which divisibility rule would you apply to tell whether a number is divisible by 3?
If the sum of the digits is a multiple of 3, the whole number is divisible by 3.
What are the divisibility rules?
1- Any number is divisible by 1.2- Any even number is divisible by 2.3- If its digits add up to a number divisible by 3, the whole number is divisible by 3.4- If the last two digits are divisible by 4, the whole number is divisible by 4.5- If it ends in 5 or 0, the whole number is divisible by 5.6- If it's even and also divisible by 3, the whole number is divisible by 6.7- There is no rule for 7.8- If the last three digits are divisible by 8, the whole number is divisible by 8.9- If its digits add up to a number divisible by 9, the whole number is divisible by 9.10- If it ends in 0, the whole number is divisible by 10.divisibilty rules are how you times the number for instence if you want to find the divisibilty rule for 10 it would be the end number must be zero and then it would be a multiple of 10 and the divisibilty rule for 2 is the end number must be even then it would be a multiple of 2There are guidelines that exist to tell whether a number is divisible by another without having to perform the division. For example, if a number ends in 0 or 5, it is divisible by 5. That's the divisibility rule for 5.You can find out if a number is divisible by another by trial and error, that is, actually dividing it. If you know the divisibility rules, you can tell whether one number is divisible by another just by looking at it. For example, if a number is even, it's divisible by 2. If the sum of a number's digits adds up to a multiple of 3, the original number is divisible by 3. If a number ends in 0 or 5, it's divisible by 5.
What is the divisibility rule of 85?
The rule is: if a number is divisible by 5 and 17 at the same time, that number is divisible by 85
Write a rule to determine when a number is divisible by 12?
A number is divisible by 12 if it is divisible by 3 AND it is divisible by 4. Rule 1a (Divisibility by 3): Add up all the digits of the number. Is this number divisible by 3? Rule 1b (Divisibility by 4): Is the number formed by the last two digits of the original number (the number left after deleting the hundreds, thousands, millions etc) divisible by 4? If the answer to 1a is NO, then the number is not divisible by 3 and so not divisible by 12. In this case, obviously, rule 1b is irrelevant. If the answer to 1b is NO, then the number is not divisible by 4 and so not divisible by 12. If the answer to both 1a and 1b is YES, then the number is divisible by 12.
What is the divisiable rule for 3 and 2?
The divisible rule for 2 is if the last digit of the number is 0,2,4,6, or 8. The divisible rule for 3 is if the last 2 digits of the number is divisible by 3,03,06,09,12,15,18,21,24,27,30,33,36,39,42,45,48,51,54,57,60,63,66,69,72,75,78,81,84,87,90,93,96, or 99.
Can 117 be divided by 2?
58.5
What is the division rule for 6?
Rule: If it is divisible by 2 and by 3Numbers are divisible by 6 if they are divisible by 3 and 2. Therefore, for example, since 18 is divisible by 3 and 2, it is also divisible by 6.The divisibility rule for 6 is, it can go into the number if 2 and 3 can also.
What is divisiblity rule for number 6?
if the number is divisible by 2 and 3 then it is divisible by 6 =D
What is the rule for multiples of 6?
If a number is divisible by 2 (an even number) and 3 (the sum of the digits is divisible by 3) then the number is divisible by 6.
What is the divisiblity rule for the number 8?
To find out if a number is divisible by 8 the number must be divisible by 2 and 4!
