145.28 is what percent of 287.63 - 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 287.63 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 287.63, so we can write it down as 100%=287.63.
4. We know, that x% equals 145.28 of the output value, so we can write it down as x%=145.28.
5. Now we have two simple equations:
1) 100%=287.63
2) x%=145.28
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%=287.63/145.28
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 145.28 is what percent of 287.63

100%/x%=287.63/145.28
(100/x)*x=(287.63/145.28)*x       - we multiply both sides of the equation by x
100=1.9798320484581*x       - we divide both sides of the equation by (1.9798320484581) to get x
100/1.9798320484581=x
50.509334909432=x
x=50.509334909432

now we have:
