71.76 is what percent of 649.99 - 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 649.99 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 649.99, so we can write it down as 100%=649.99.
4. We know, that x% equals 71.76 of the output value, so we can write it down as x%=71.76.
5. Now we have two simple equations:
1) 100%=649.99
2) x%=71.76
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%=649.99/71.76
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 71.76 is what percent of 649.99

100%/x%=649.99/71.76
(100/x)*x=(649.99/71.76)*x       - we multiply both sides of the equation by x
100=9.0578316610925*x       - we divide both sides of the equation by (9.0578316610925) to get x
100/9.0578316610925=x
11.040169848767=x
x=11.040169848767

now we have:
