5 is what percent of 231.2 - step by step solution

To get the solution, we are looking for, we need to point out what we know.

1. We assume, that the number 231.2 is 100% - because it's the output value of the task.
2. We assume, that x is the value we are looking for.
3. If 100% equals 231.2, so we can write it down as 100%=231.2.
4. We know, that x% equals 5 of the output value, so we can write it down as x%=5.
5. Now we have two simple equations:
1) 100%=231.2
2) x%=5
where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
100%/x%=231.2/5
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 5 is what percent of 231.2

100%/x%=231.2/5
(100/x)*x=(231.2/5)*x       - we multiply both sides of the equation by x
100=46.24*x       - we divide both sides of the equation by (46.24) to get x
100/46.24=x
2.1626297577855=x
x=2.1626297577855

now we have:
5 is 2.1626297577855% of 231.2
