5 is what percent of 723 - 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 723 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 723, so we can write it down as 100%=723.
4. We know, that x% equals 5 of the output value, so we can write it down as x%=5.
5. Now we have two simple equations:
1) 100%=723
2) x%=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%=723/5
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 5 is what percent of 723

100%/x%=723/5
(100/x)*x=(723/5)*x       - we multiply both sides of the equation by x
100=144.6*x       - we divide both sides of the equation by (144.6) to get x
100/144.6=x
0.69156293222683=x
x=0.69156293222683

now we have:
5 is 0.69156293222683% of 723
