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.


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 a number divisible by six is also divisible by three?

Yes


Is it true that every number has at least 2 divisors?

Yes. Every number is divisible by itself or 1.


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


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 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 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 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.


What is true of all multiples of the number 6?

All multiples of the number 6 are also divisible by both 2 and 3.


Is this biconditional statement true A number is divisible by 6 if and only if it is divisible by 3?

How can the following definition be written correctly as a biconditional statement? An odd integer is an integer that is not divisible by two. (A+ answer) An integer is odd if and only if it is not divisible by two


What is a number n where if the sum of the digits of the number is divisible by n, then the number itself is divisible by n?

(The assumes that "the number" in the question is not n, although if they are they same number, this is still true.) "If the sum of the digits of the number is divisible by n, then the number itself is divisible by n" is true if n is 3 or if n is 9.


Is this fact true A whole number is divisible by 3 if the sum of its digits is divisible by 3?

True fact.


is this biconditional true or falseA number is even if and only if it is divisible by 2.?

true


Why is that when a number is divisible by 2 and divisible by3 it is also by six how are they related why does this pattern not work for 2 4and 8?

Numbers divisible by 6 will have at least one 2 and one 3 as prime factors because 2 x 3 = 6. The same is true for 2, 4 and 8. Numbers divisible by 4 are also divisible by 2. Numbers divisible by 8 are also divisible by 4 and 2.


Are all numbers divisible by 5 also divisible by 10?

No, but the reverse is true.


Is it true that if a number is divisible by 3 then it must be an odd number?

no 6 is divisible by 3 and so is 24 and so on ! lol


What is the smallest number that can be divisible by all integers?

There does not exist a number that is divisible by all integers. The opposite is true. The number one can divided into all integers.


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


What is the divisibility rule for 4 and 6?

The Rule for 4 is if the last 2 numbers are divisible by 4 (The tens and ones place) For example. 10759283740 is divisible, while 10759283738 is not, because 4 does not go into 38. The rule for 6 is if the number is even and also divisible by 3. If this is true, then the number is divisible by 6.


Is the only even prime number is 2 t or f?

Yes, it is true that 2 is the only even prime number. All even numbers are evenly divisible by 2 (that is the definition of an even number). The number 2 is also divisible by 2, however, prime numbers, like all numbers, are evenly divisible by themselves, so that does not disqualify 2 from being a prime number.


What is the number that is divisible by 10 and 3 but not 5?

Three is a prime number and isn't divisible by any whole number * * * * * True, but irrelevant to the question. Any number that is divisible by 10 MUST be divisible by 5. Therefore there are no such numbers.


Is Every real number is also rational true or false?

False.
