3117.68 is what percent of 1978.4 - 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 1978.4 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 1978.4, so we can write it down as 100%=1978.4.
4. We know, that x% equals 3117.68 of the output value, so we can write it down as x%=3117.68.
5. Now we have two simple equations:
1) 100%=1978.4
2) x%=3117.68
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%=1978.4/3117.68
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 3117.68 is what percent of 1978.4

100%/x%=1978.4/3117.68
(100/x)*x=(1978.4/3117.68)*x       - we multiply both sides of the equation by x
100=0.63457442713813*x       - we divide both sides of the equation by (0.63457442713813) to get x
100/0.63457442713813=x
157.58592802264=x
x=157.58592802264

now we have:
