71.5 is what percent of 410 - 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 410 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 410, so we can write it down as 100%=410.
4. We know, that x% equals 71.5 of the output value, so we can write it down as x%=71.5.
5. Now we have two simple equations:
1) 100%=410
2) x%=71.5
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%=410/71.5
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 71.5 is what percent of 410

100%/x%=410/71.5
(100/x)*x=(410/71.5)*x       - we multiply both sides of the equation by x
100=5.7342657342657*x       - we divide both sides of the equation by (5.7342657342657) to get x
100/5.7342657342657=x
17.439024390244=x
x=17.439024390244

now we have:
71.5 is 17.439024390244% of 410
