When its digital root is 9 (divisible by 9) and it is even (divisible by 2). The digital root of a number is calculated by adding up all the digits in a number. If the answer is greater than 9, then repeat until you get an answer that is a single digit.

One way to find out is to try it. Firstly, any number is divisible by any number except zero. If you try this example you get 37 exactly. So it is divisible by 6 with no remainder. * * * * * A simpler method to test divisibility by 6: Step 1: Is the number even? That is, does it end with 0, 2, 4, 6 or 8? If yes, then it is divisible by 2. Step 2: Add all the digits together. If the answer is bigger than 10, repeat (and repeat again if needed). If the final answer 3, 6 or 9 the number is divisible by 3. If the number is divisible by 2 and by 3, then it is divisible by 6.

7/8 is a rational number because rational numbers are fractions, numbers that terminate, numbers that repeat.

that is called an irrational number

Subtract 5 times the last digit from remaining truncated number. Repeat the step as necessary. If the result is divisible by 17, the original number is also divisible by 17

The only prime between 8 and 12 is 11.To find out if a number is prime, just try dividing it by all prime numbers between 2 and that number (including 2). The easiest method to do this is to write all numbers from 2 to your number down. Then cross out all numbers divisible by 2. Now cross out all numbers divisible by the next lowest number that is not crossed out (which is 3). Repeat this last step (the next number should be 5, then 7, then 11) until you reach your number, or you cross it out. If you have crossed it out, it is not a prime number, and if it has not been crossed out it is a prime number.

If you can repeat the numbers within the combination there are 10,000 different combinations. If you cannot repeat the numbers within the combination, there are 5040 different combinations.

Rational. Because it repeats. (Rational numbers either repeat or stop. Irrational numbers don't stop or repeat, such as pi)

A number is divisible by 55 if it is divisible by both 5 and 11. 5- If the last digit is 0 or 5 11- Alternately add and subtract all digits of a number starting with subtraction. Repeat this process for larger numbers. Ex: 568,370, 18,832,055 Non Ex: 572, 4815

#1 n := 3 #2 print n #3 n := n + 6 #4 repeat from #2

Sorry but the list to that question goes on forever, but I can point out this: If you're dealing with a large number and you want to know if it is divisible, just add up the digits and see if that number is divisible, if you still don't know, repeat the process. For Example: 684/3= 6+8+4= 18/3= 1+8= 9/3= 3

To be divisible by 9, sum the digits of the number and if this sum is divisible by 9, then the original number is divisible by 9. As the test can be repeated on the sum, repeat the summing until a single digit remains; only if this number is 9 is the original number divisible by 9. For 516 this gives: → 5 + 1 + 6 = 12 → 1 + 2 = 3 3 is not 9 so 516 is not divisible by 9. (This single digit is known as the digital root of the number.)

1) Get the minimum number 2) get the maximum number 3) start at the minimum number 4) is it divisible by three but not by six? If yes, jump to step 5 If no, increment by 1 and repeat step 4 5) output the current number 6) increment the number by six 7)is it greater than or equal to our maximum number? if yes, end the program if no, jump to step 5

Yes. Rational numbers are numbers or decimals that repeat or terminate. Irrational numbers do not. For example π is an irrational number.

Sure. Different Girl Scout councils can repeat troop numbers from other councils, but never the same troop number in the same council.

If they can repeat, then: 17^6=24,137,569 If they can't repeat, then: 17*16*15*14*13*12=8,910,720

Numbers that never repeat or terminate are called irrational numbers. Pi is one example.

10P4 = 5040

Not evenly. It divides to 67.2 repeat.

50,004There is a method called "casting out nines" that can be used to quickly test if any positive number is divisible by 9. To perform this test add the digits of the number, if the result has more than one digit repeat the addition of the digits, when the result is a single digit if that digit is 9 then the number is divisible by nine.Examples:99999, gives 45, gives 9, is divisible by 912345, gives 15, gives 6, is not divisible by 910008, gives 9, is divisible by 950004, gives 9, is divisible by 930303, gives 9, is divisible by 933633, gives 18, gives 9, is divisible by 9etc.

6 + 4 + 6 = 16 1 + 6 = 7 → No; 646 is not divisible by 9 (there is a remainder of 7). ----------------------------------------- Only if the sum of the digits is divisible by 9 is the original number divisible by 9. Repeat the test on the sum until a single digit remains; only if this single digit is 9 is the original number divisible by 9, otherwise this single digit is the remainder when the original number is divided by 9.

They primes between 30 and 50 are 31, 37, 41, 43 and 47. To find this, first remove all even numbers between 30 and 50 as all even numbers can be made by multiplying 2 and some integer. This leaves. 31, 33, 35, 37, 39, 41, 43, 45, 47 and 49. Next, remove all numbers divisible by 3. This removes 33 and 39 because 3 * 11 = 33 and 3 * 13 = 39. Now, the same thing with 5. Any number that ends in 0 or 5 is divisible by 5, so 35 and 45 can be removed. Now we remove any numbers divisible by 7. 49 is, so we remove it.To find out if a number is prime, just try dividing it by all prime numbers between 2 and that number (including 2). The easiest method to do this is to write all numbers from 2 to your number down. Then cross out all numbers divisible by 2. Now cross out all numbers divisible by the next lowest number that is not crossed out (which is 3). Repeat this last step (the next number should be 5, then 7, then 11) until you reach your number, or you cross it out. If you have crossed it out, it is not a prime number, and if it has not been crossed out it is a prime number.

The number of combinations of six numbers that can be made from seven numbers will depend on if you can repeat numbers. In all there are over 2,000 different numbers that can be made.
