38.91 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 38.91 of the output value, so we can write it down as x%=38.91.
5. Now we have two simple equations:
1) 100%=350
2) x%=38.91
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%=350/38.91
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 38.91 is what percent of 350

100%/x%=350/38.91
(100/x)*x=(350/38.91)*x       - we multiply both sides of the equation by x
100=8.9951169365202*x       - we divide both sides of the equation by (8.9951169365202) to get x
100/8.9951169365202=x
11.117142857143=x
x=11.117142857143

now we have:
38.91 is 11.117142857143% of 350
