5 divided by what equals 8?

5 divided by what equals 8? If you're looking to solve this word problem then you're in the right place. If you have the number 5 and you want to divide it by something to get the answer 8 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:

5 / X =   8

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:

5(X) / X =   8(X)

If you're new to equations this might look a little confusing but all we are really saying is that 5 is the same as 8 times X.

To find X, we need to divide both sides by our final answer, 8:

5 / 8 =   8(X) / 8

So, our final answer here to 5 divided by what equals 8 is:

0.625 = 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 5 by 0.625:

5 / 0.625 = 8

Hopefully now you know exactly how to work out math problems like these yourself in future. Could I have just told you to divide 5 by 8? 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.
