53 is what percent of 819 - 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 819 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 819, so we can write it down as 100%=819.
4. We know, that x% equals 53 of the output value, so we can write it down as x%=53.
5. Now we have two simple equations:
1) 100%=819
2) x%=53
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%=819/53
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 53 is what percent of 819

100%/x%=819/53
(100/x)*x=(819/53)*x       - we multiply both sides of the equation by x
100=15.452830188679*x       - we divide both sides of the equation by (15.452830188679) to get x
100/15.452830188679=x
6.4713064713065=x
x=6.4713064713065

now we have:
53 is 6.4713064713065% of 819
