727.86 is what percent of 4121.7 - 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 4121.7 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 4121.7, so we can write it down as 100%=4121.7.
4. We know, that x% equals 727.86 of the output value, so we can write it down as x%=727.86.
5. Now we have two simple equations:
1) 100%=4121.7
2) x%=727.86
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%=4121.7/727.86
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 727.86 is what percent of 4121.7

100%/x%=4121.7/727.86
(100/x)*x=(4121.7/727.86)*x       - we multiply both sides of the equation by x
100=5.6627648174099*x       - we divide both sides of the equation by (5.6627648174099) to get x
100/5.6627648174099=x
17.659218283718=x
x=17.659218283718

now we have:
