30.83 is what percent of 657.66 - 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 657.66 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 657.66, so we can write it down as 100%=657.66.
4. We know, that x% equals 30.83 of the output value, so we can write it down as x%=30.83.
5. Now we have two simple equations:
1) 100%=657.66
2) x%=30.83
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%=657.66/30.83
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 30.83 is what percent of 657.66

100%/x%=657.66/30.83
(100/x)*x=(657.66/30.83)*x       - we multiply both sides of the equation by x
100=21.331819656179*x       - we divide both sides of the equation by (21.331819656179) to get x
100/21.331819656179=x
4.6878326186783=x
x=4.6878326186783

now we have:
