309.29 is what percent of 377 - 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 377 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 377, so we can write it down as 100%=377.
4. We know, that x% equals 309.29 of the output value, so we can write it down as x%=309.29.
5. Now we have two simple equations:
1) 100%=377
2) x%=309.29
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%=377/309.29
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 309.29 is what percent of 377

100%/x%=377/309.29
(100/x)*x=(377/309.29)*x       - we multiply both sides of the equation by x
100=1.2189207539849*x       - we divide both sides of the equation by (1.2189207539849) to get x
100/1.2189207539849=x
82.039787798408=x
x=82.039787798408

now we have:
309.29 is 82.039787798408% of 377
