Is it true that a number divisible by 9 and 3 also divisible by 6?

No
3x9 = 27
27 / 6 = 4
Or even 9 is divisible by 3 and 9 but not 6. 6 would be 1.5 so although you can divide them by 6 the answer isn't a whole number. If you multiply a number with 6 in it then the numbers will end in 2, 4, 6, 8, 0 which are all even numbers. This is because 6 is an even number which means that anything you multiply with you will get an even number. Never an odd. Try it on a calculator and see if it works. I know I'm right anyways, not bragging or anything

If a number is even and divisible by 3 than what is true about that number?
If a number is even (divisible by 2) and divisible by 3, then it must also be divisible by 6.
Is it true or false that a number is divisible by 6 if and only if it is divisible by 3?
False. The question consists of two parts: - a number is divisible by 6 if it is divisible by 3? False. It must also be divisible by 2. - a number is divisible by 6 only if it is divisible by 3? This is true but the false part makes the whole statement false.
Is 1 trillion 17 a prime number?
Since the sum of the digits is divisible by 3, the original number is also divisible by 3.Since the sum of the digits is divisible by 3, the original number is also divisible by 3.Since the sum of the digits is divisible by 3, the original number is also divisible by 3.Since the sum of the digits is divisible by 3, the original number is also divisible by 3.
Is every number that is divisible by 6 divisible by 3?
Yes, it's true. 3 is one of the factors of 6, so any number that has six as a factor also has 3 as a factor.
What number is divisible by 6 also a multiple of 3?
As 6 is divisible by 3, ANY dumber divisible by 6 is also therefore divisible by 3. Any number divisible by 3 is ALSO a multiple of 3.
A number is divisible by 6 if and only if it is divisible by 3?
If this is a T-F question, the answer is false. It is true that if a number is divisible by 6, it also divisible by 3. This is true because 6 is divisible by 3. However, the converse -- If a number is divisible by 3, it is divisible by 6, is false. A counterexample is 15. 15 is divisible by 3, but not by 6. It becomes clearer if you split the question into its two parts. A number is divisible by 6 if it is divisible by 3? False. It must also be divisible by 2. A number is divisible by 6 only if it is divisible by 3? True.
If a number is even and divisible by 3 than what is true about that number?
If a number is even (divisible by 2) and divisible by 3, then it must also be divisible by 6.
If a number is is divisible by 2 and 3 is it also divisible by 6?
Yes, that is true.
Is every number divisible by 3 and 9 is also divisible by 6 is this true?
No, 9 is divisible by 3 and 9, but not six 3 x 9 = 27, also not divisible by 6
Is it true that a number divisible by 3is also divisible by 9?
Not always because 33 is divisible by 3 but not by 9
Is it true or false that a number is divisible by 6 if and only if it is divisible by 3?
False. The question consists of two parts: - a number is divisible by 6 if it is divisible by 3? False. It must also be divisible by 2. - a number is divisible by 6 only if it is divisible by 3? This is true but the false part makes the whole statement false.

Is this fact true A whole number is divisible by 3 if the sum of its digits is divisible by 3?
True fact.
Is it true that 558 is divisible by 3?
Yes, it is true 558/3 = 186 To find out if a number is divisible by 3, add the digits; if the sum is divisible by 3, so is the number 5+5+8 = 18 which is divisible by 3
Is every number that is divisible by 6 divisible by 3?
Yes, it's true. 3 is one of the factors of 6, so any number that has six as a factor also has 3 as a factor.
What number is divisible by 6 also a multiple of 3?
As 6 is divisible by 3, ANY dumber divisible by 6 is also therefore divisible by 3. Any number divisible by 3 is ALSO a multiple of 3.
What is the converse of the sentence A number divisible by 9 is also divisible by 3?
If a number is not divisible by 3 then it is not divisible by 9.
