Always. A number divisible by another is also divisible by all the factors of that number. A number that is divisible by 10 is also divisible by 2 and 5. Take any multiple of 10 and check it. 70/5=14 or 180/5=36

Any number that is divisible by 10 is an even number and hence divisible by 2 also. It can also be stated that because 10 is divisible by 2, all numbers divisble by 10 are also divisible by 2.

No. 15, 25, 35, and 1675 are divisible by 5, but not by 10. However, every number divisible by 10 is also divisible by 5.

Yes, since 10 is divisible by 5. Likewise, every number which is divisible by 9 is also divisible by 3.

Yes.

How about: 30

If a number is divisible by 10 (i.e. 100) then it is also divisible by 5. Ex: 100 by 10, is 10 by 5, is 20 20 by 10 is 2 by 5 is 4 The number of times it is divisible by 5 will always be double the number of times it is divisible by 10, which makes sense because 10 is double 5.

Use the divisibility rule for 10. If the number is divisible by 10, then it is obviously also divisible by 5.

There are no numbers that satisfy this. If a number is divisible by both 2 and 5, then it must also be divisible by 10.

If a number ends with 0, it is divisible by 10.If a number ends with 0, it is divisible by 10.If a number ends with 0, it is divisible by 10.If a number ends with 0, it is divisible by 10.

Every number divisible by 10 is divisible by 5.

There are a great many facts about the number 10 such as the fact that it is divisible by 5. It is also divisible by the number 2.
