290.3 is what percent of 350 - 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 350 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 350, so we can write it down as 100%=350.
4. We know, that x% equals 290.3 of the output value, so we can write it down as x%=290.3.
5. Now we have two simple equations:
1) 100%=350
2) x%=290.3
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%=350/290.3
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 290.3 is what percent of 350

100%/x%=350/290.3
(100/x)*x=(350/290.3)*x       - we multiply both sides of the equation by x
100=1.2056493282811*x       - we divide both sides of the equation by (1.2056493282811) to get x
100/1.2056493282811=x
82.942857142857=x
x=82.942857142857

now we have:
290.3 is 82.942857142857% of 350
