51.6 is what percent of 830 - 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 830 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 830, so we can write it down as 100%=830.
4. We know, that x% equals 51.6 of the output value, so we can write it down as x%=51.6.
5. Now we have two simple equations:
1) 100%=830
2) x%=51.6
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%=830/51.6
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 51.6 is what percent of 830

100%/x%=830/51.6
(100/x)*x=(830/51.6)*x       - we multiply both sides of the equation by x
100=16.085271317829*x       - we divide both sides of the equation by (16.085271317829) to get x
100/16.085271317829=x
6.2168674698795=x
x=6.2168674698795

now we have:
51.6 is 6.2168674698795% of 830
