1197.81 is what percent of 1999 - 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 1999 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 1999, so we can write it down as 100%=1999.
4. We know, that x% equals 1197.81 of the output value, so we can write it down as x%=1197.81.
5. Now we have two simple equations:
1) 100%=1999
2) x%=1197.81
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%=1999/1197.81
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 1197.81 is what percent of 1999

100%/x%=1999/1197.81
(100/x)*x=(1999/1197.81)*x       - we multiply both sides of the equation by x
100=1.6688790375769*x       - we divide both sides of the equation by (1.6688790375769) to get x
100/1.6688790375769=x
59.920460230115=x
x=59.920460230115

now we have:
1197.81 is 59.920460230115% of 1999
