821.25 is what percent of 1151.4 - 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 1151.4 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 1151.4, so we can write it down as 100%=1151.4.
4. We know, that x% equals 821.25 of the output value, so we can write it down as x%=821.25.
5. Now we have two simple equations:
1) 100%=1151.4
2) x%=821.25
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%=1151.4/821.25
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 821.25 is what percent of 1151.4

100%/x%=1151.4/821.25
(100/x)*x=(1151.4/821.25)*x       - we multiply both sides of the equation by x
100=1.4020091324201*x       - we divide both sides of the equation by (1.4020091324201) to get x
100/1.4020091324201=x
71.326211568525=x
x=71.326211568525

now we have:
821.25 is 71.326211568525% of 1151.4
