71.5 is what percent of 2179.5 - 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 2179.5 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 2179.5, so we can write it down as 100%=2179.5.
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%=2179.5
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%=2179.5/71.5
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 2179.5

100%/x%=2179.5/71.5
(100/x)*x=(2179.5/71.5)*x       - we multiply both sides of the equation by x
100=30.482517482517*x       - we divide both sides of the equation by (30.482517482517) to get x
100/30.482517482517=x
3.2805689378298=x
x=3.2805689378298

now we have:
71.5 is 3.2805689378298% of 2179.5
