814.85 is what percent of 840 - 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 840 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 840, so we can write it down as 100%=840.
4. We know, that x% equals 814.85 of the output value, so we can write it down as x%=814.85.
5. Now we have two simple equations:
1) 100%=840
2) x%=814.85
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%=840/814.85
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 814.85 is what percent of 840

100%/x%=840/814.85
(100/x)*x=(840/814.85)*x       - we multiply both sides of the equation by x
100=1.0308645763024*x       - we divide both sides of the equation by (1.0308645763024) to get x
100/1.0308645763024=x
97.005952380952=x
x=97.005952380952

now we have:
814.85 is 97.005952380952% of 840
