155.13 is what percent of 200 - 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 200 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 200, so we can write it down as 100%=200.
4. We know, that x% equals 155.13 of the output value, so we can write it down as x%=155.13.
5. Now we have two simple equations:
1) 100%=200
2) x%=155.13
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%=200/155.13
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 155.13 is what percent of 200

100%/x%=200/155.13
(100/x)*x=(200/155.13)*x       - we multiply both sides of the equation by x
100=1.2892412815058*x       - we divide both sides of the equation by (1.2892412815058) to get x
100/1.2892412815058=x
77.565=x
x=77.565

now we have:
155.13 is 77.565% of 200
