821.8 is what percent of 970 - 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 970 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 970, so we can write it down as 100%=970.
4. We know, that x% equals 821.8 of the output value, so we can write it down as x%=821.8.
5. Now we have two simple equations:
1) 100%=970
2) x%=821.8
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%=970/821.8
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 821.8 is what percent of 970

100%/x%=970/821.8
(100/x)*x=(970/821.8)*x       - we multiply both sides of the equation by x
100=1.1803358481382*x       - we divide both sides of the equation by (1.1803358481382) to get x
100/1.1803358481382=x
84.721649484536=x
x=84.721649484536

now we have:
821.8 is 84.721649484536% of 970
