519 is what percent of 7 - 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 7 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 7, so we can write it down as 100%=7.
4. We know, that x% equals 519 of the output value, so we can write it down as x%=519.
5. Now we have two simple equations:
1) 100%=7
2) x%=519
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%=7/519
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 519 is what percent of 7

100%/x%=7/519
(100/x)*x=(7/519)*x       - we multiply both sides of the equation by x
100=0.013487475915222*x       - we divide both sides of the equation by (0.013487475915222) to get x
100/0.013487475915222=x
7414.2857142857=x
x=7414.2857142857

now we have:
519 is 7414.2857142857% of 7
