290.67 is what percent of 1331.39 - 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 1331.39 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 1331.39, so we can write it down as 100%=1331.39.
4. We know, that x% equals 290.67 of the output value, so we can write it down as x%=290.67.
5. Now we have two simple equations:
1) 100%=1331.39
2) x%=290.67
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%=1331.39/290.67
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 290.67 is what percent of 1331.39

100%/x%=1331.39/290.67
(100/x)*x=(1331.39/290.67)*x       - we multiply both sides of the equation by x
100=4.5804176557608*x       - we divide both sides of the equation by (4.5804176557608) to get x
100/4.5804176557608=x
21.832070242378=x
x=21.832070242378

now we have:
290.67 is 21.832070242378% of 1331.39
