270.5 is what percent of 343 - 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 343 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 343, so we can write it down as 100%=343.
4. We know, that x% equals 270.5 of the output value, so we can write it down as x%=270.5.
5. Now we have two simple equations:
1) 100%=343
2) x%=270.5
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%=343/270.5
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 270.5 is what percent of 343

100%/x%=343/270.5
(100/x)*x=(343/270.5)*x       - we multiply both sides of the equation by x
100=1.268022181146*x       - we divide both sides of the equation by (1.268022181146) to get x
100/1.268022181146=x
78.862973760933=x
x=78.862973760933

now we have:
270.5 is 78.862973760933% of 343
