314.76 is what percent of 4200 - 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 4200 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 4200, so we can write it down as 100%=4200.
4. We know, that x% equals 314.76 of the output value, so we can write it down as x%=314.76.
5. Now we have two simple equations:
1) 100%=4200
2) x%=314.76
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%=4200/314.76
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 314.76 is what percent of 4200

100%/x%=4200/314.76
(100/x)*x=(4200/314.76)*x       - we multiply both sides of the equation by x
100=13.343499809379*x       - we divide both sides of the equation by (13.343499809379) to get x
100/13.343499809379=x
7.4942857142857=x
x=7.4942857142857

now we have:
314.76 is 7.4942857142857% of 4200
