570 is what percent of 1970 - 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 1970 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 1970, so we can write it down as 100%=1970.
4. We know, that x% equals 570 of the output value, so we can write it down as x%=570.
5. Now we have two simple equations:
1) 100%=1970
2) x%=570
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%=1970/570
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 570 is what percent of 1970

100%/x%=1970/570
(100/x)*x=(1970/570)*x       - we multiply both sides of the equation by x
100=3.4561403508772*x       - we divide both sides of the equation by (3.4561403508772) to get x
100/3.4561403508772=x
28.934010152284=x
x=28.934010152284

now we have:
570 is 28.934010152284% of 1970
