A number is divisible by 9 if a whole number of 9s can go into it and leave no remainder.
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.
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.
It is the fact that 13*5 = 65.

A number is divisible by 9 if a whole number of 9s can go into it and leave no remainder.
Yes. Any number ending in 0 is divisible by 10, which automatically makes it divisible by 5 as well.
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.
Yes, if the number is divisible by 20 then it has to be even. Typically if a number is divisible by any number ending in zero (10, 20, 30, etc), the number itself ends in zero as well, which makes it even.
72/2 = 36.
The concept of divisibility makes sense only in the context of integers. Otherwise every number is divisible by every non-zero number.
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.
To determine what number makes 371 divisible by 3, we need to sum the digits of 371: 3 + 7 + 1 = 11. To be divisible by 3, the sum of the digits must also be divisible by 3. Since 11 is not divisible by 3, we need to find the number that, when added to 11, results in a sum divisible by 3. The next multiple of 3 greater than 11 is 12, so the number that makes 371 divisible by 3 is 1.
It is the fact that 13*5 = 65.
The concept of divisible and non-divisible makes sense only in the context of whole numbers. Once you allow fractions (or their decimal representations), every number is divisible by any non-zero number.
