57 is what percent of 2030 - 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 2030 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 2030, so we can write it down as 100%=2030.
4. We know, that x% equals 57 of the output value, so we can write it down as x%=57.
5. Now we have two simple equations:
1) 100%=2030
2) x%=57
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%=2030/57
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 57 is what percent of 2030

100%/x%=2030/57
(100/x)*x=(2030/57)*x       - we multiply both sides of the equation by x
100=35.614035087719*x       - we divide both sides of the equation by (35.614035087719) to get x
100/35.614035087719=x
2.807881773399=x
x=2.807881773399

now we have:
57 is 2.807881773399% of 2030
