4.2 is what percent of 570 - 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 570 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 570, so we can write it down as 100%=570.
4. We know, that x% equals 4.2 of the output value, so we can write it down as x%=4.2.
5. Now we have two simple equations:
1) 100%=570
2) x%=4.2
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%=570/4.2
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 4.2 is what percent of 570

100%/x%=570/4.2
(100/x)*x=(570/4.2)*x       - we multiply both sides of the equation by x
100=135.71428571429*x       - we divide both sides of the equation by (135.71428571429) to get x
100/135.71428571429=x
0.73684210526316=x
x=0.73684210526316

now we have:
4.2 is 0.73684210526316% of 570
