4 is what percent of 571.3 - 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 571.3 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 571.3, so we can write it down as 100%=571.3.
4. We know, that x% equals 4 of the output value, so we can write it down as x%=4.
5. Now we have two simple equations:
1) 100%=571.3
2) x%=4
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%=571.3/4
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 4 is what percent of 571.3

100%/x%=571.3/4
(100/x)*x=(571.3/4)*x       - we multiply both sides of the equation by x
100=142.825*x       - we divide both sides of the equation by (142.825) to get x
100/142.825=x
0.70015753544548=x
x=0.70015753544548

now we have:
4 is 0.70015753544548% of 571.3
