28.3 is what percent of 231.8 - 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 231.8 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 231.8, so we can write it down as 100%=231.8.
4. We know, that x% equals 28.3 of the output value, so we can write it down as x%=28.3.
5. Now we have two simple equations:
1) 100%=231.8
2) x%=28.3
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%=231.8/28.3
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 28.3 is what percent of 231.8

100%/x%=231.8/28.3
(100/x)*x=(231.8/28.3)*x       - we multiply both sides of the equation by x
100=8.1908127208481*x       - we divide both sides of the equation by (8.1908127208481) to get x
100/8.1908127208481=x
12.20880069025=x
x=12.20880069025

now we have:
28.3 is 12.20880069025% of 231.8
