Is 81 Divisible By 10?
In this quick and easy guide, we'll work out whether 81 is divisible by 10. There are some simple rules we can follow to decide whether one number is divisible by another without ever needing to even do the division!
First up, let's clarify what we mean by "81 is divisible by 10". What we want to check is whether 81 can be divided by 10 without any remainder (i.e the answer is a whole number).
Ah, 10. The easiest number to check divisibility of. I'm sure you know already that if the number ends in a 0, then it is divisible by 10.
We can see that 81 DOES NOT end with a 0, which means that 81 IS NOT divisible by 10.
Another way you can figure out if 81 is divisible by 10 is by actually doing the calculation and dividing 81 by 10:
As you can see, when we do this division we have a decimal of 0.1. Since the division does not result in a whole number, this shows us that 81 is not divisible by 10.
Hopefully now you know exactly how to work out whether one number is divisible by another. Could I have just told you to divide 81 by 10 and check if it is a whole number? Yes, but aren't you glad you learned the process?
Give this a go for yourself and try to calculate a couple of these without using our calculator. Grab a pencil and a piece of paper and pick a couple of numbers to try it with.
