69.1 is what percent of 686.93 - 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 686.93 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 686.93, so we can write it down as 100%=686.93.
4. We know, that x% equals 69.1 of the output value, so we can write it down as x%=69.1.
5. Now we have two simple equations:
1) 100%=686.93
2) x%=69.1
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%=686.93/69.1
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 69.1 is what percent of 686.93

100%/x%=686.93/69.1
(100/x)*x=(686.93/69.1)*x       - we multiply both sides of the equation by x
100=9.9410998552822*x       - we divide both sides of the equation by (9.9410998552822) to get x
100/9.9410998552822=x
10.059249122909=x
x=10.059249122909

now we have:
69.1 is 10.059249122909% of 686.93
