A number is divisible by if the units digit is even - that is, it divides by without a remainder.
A number is divisible by if the units digit is even - that is, it divides by without a remainder.
First way: A number is divisible by if its last two digits are divisible by .
Second way: Multiply the tens digit by and add the units digit. If the result obtained is a multiple of , then the original number is as well.
A number is divisible by if its units digit is .
If a number is divisible by 10, is it also therefore divisible by 2?
Is the number 43 divisible by 4?
Is the number 42 divisible by 2?
Is the number 30 divisible by 10?
Is the number 8 divisible by 2?
If a number is divisible by 10, is it also therefore divisible by 2?
The answer is yes - every number that is divisible by 10 is divisible by 2.
This can be learned through the divisibility rules of each number.
We know that to identify a number divisible by 10, we need to examine its ones digit,
only numbers whose ones digit is 0 are divisible by 10,
for example: 30, 510, 15610
We know that numbers whose ones digit is 0 are actually even numbers,
and even numbers are divisible by 2 without a remainder.
Therefore, we can be certain - every number that is divisible by 10 is also divisible by 2.
It's important to understand that this is not necessarily true in reverse, not every number that is divisible by 2 is also divisible by 10!
