0.71 is what percent of 3900.64 - 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 3900.64 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 3900.64, so we can write it down as 100%=3900.64.
4. We know, that x% equals 0.71 of the output value, so we can write it down as x%=0.71.
5. Now we have two simple equations:
1) 100%=3900.64
2) x%=0.71
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%=3900.64/0.71
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 0.71 is what percent of 3900.64

100%/x%=3900.64/0.71
(100/x)*x=(3900.64/0.71)*x       - we multiply both sides of the equation by x
100=5493.8591549296*x       - we divide both sides of the equation by (5493.8591549296) to get x
100/5493.8591549296=x
0.018202141187087=x
x=0.018202141187087

now we have:
0.71 is 0.018202141187087% of 3900.64
