Is it true that a number divisible by six is also divisible by three?
Yes
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 that every number has at least 2 divisors?
Yes. Every number is divisible by itself or 1.
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.
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 is divisible by 2 and 3 is it also divisible by 6?
Yes, that is true.
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 it true or false that any number that is divisible by 6 is divisible by 2?
True. Since 6 is divisible by 2, any number that is divisible by 6 will automatically be divisible by 2.
Is it true that a number is divisible by 8 if it divisible by 4 and divisible by 2?
Being divisible by 4, means that it will also be divisible by 2, so that doesn't tell you anything about divisibility by 8. But if you divide the number by 2, and this quotient is divisible by 4, then yes the original number is divisible by 8.
Is any number that is divisible by 2 also divisible by 6?
A number that is divisible by 2 is not always evenly divisible by 6. It must also be divisible by 3, and must not be smaller than 6. The numbers 2, 4, 8, 10, 14, 16, 20, 22, 26, and 28 etc. are all divisible by 2 but not (evenly) by 6. The opposite is true, though. Any number divisible by 6 is also divisible by 2.
Is this fact true A whole number is divisible by 3 if the sum of its digits is divisible by 3?
True fact.
