1 divided by what equals 9?

1 divided by what equals 9? If you're looking to solve this word problem then you're in the right place. If you have the number 1 and you want to divide it by something to get the answer 9 then this quick equation lesson will show you exactly how to find that missing number "something".

First of all, we can write this problem out and use the letter X to be the missing number we want to try and find:

The first step is to multiply both sides of this equation by the missing number X. We don't know what X is yet, so we do this by adding X in brackets:

If you're new to equations this might look a little confusing but all we are really saying is that 1 is the same as 9 times X.

To find X, we need to divide both sides by our final answer, 9:

So, our final answer here to 1 divided by what equals 9 is:

0.1111 = X

In these answers we round them to a maximum of 4 decimal places because some calculations might have long decimal answers. If you want to check whether the answer is close, you can divide 1 by 0.1111:

Hopefully now you know exactly how to work out math problems like these yourself in future. Could I have just told you to divide 1 by 9? 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.
