291.7 is what percent of 729 - 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 729 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 729, so we can write it down as 100%=729.
4. We know, that x% equals 291.7 of the output value, so we can write it down as x%=291.7.
5. Now we have two simple equations:
1) 100%=729
2) x%=291.7
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%=729/291.7
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 291.7 is what percent of 729

100%/x%=729/291.7
(100/x)*x=(729/291.7)*x       - we multiply both sides of the equation by x
100=2.4991429550908*x       - we divide both sides of the equation by (2.4991429550908) to get x
100/2.4991429550908=x
40.013717421125=x
x=40.013717421125

now we have:
291.7 is 40.013717421125% of 729
