135.6 is what percent of 697 - 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 697 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 697, so we can write it down as 100%=697.
4. We know, that x% equals 135.6 of the output value, so we can write it down as x%=135.6.
5. Now we have two simple equations:
1) 100%=697
2) x%=135.6
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%=697/135.6
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 135.6 is what percent of 697

100%/x%=697/135.6
(100/x)*x=(697/135.6)*x       - we multiply both sides of the equation by x
100=5.1401179941003*x       - we divide both sides of the equation by (5.1401179941003) to get x
100/5.1401179941003=x
19.454806312769=x
x=19.454806312769

now we have:
135.6 is 19.454806312769% of 697
