19.69 is what percent of 9.31 - 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 9.31 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 9.31, so we can write it down as 100%=9.31.
4. We know, that x% equals 19.69 of the output value, so we can write it down as x%=19.69.
5. Now we have two simple equations:
1) 100%=9.31
2) x%=19.69
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%=9.31/19.69
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 19.69 is what percent of 9.31

100%/x%=9.31/19.69
(100/x)*x=(9.31/19.69)*x       - we multiply both sides of the equation by x
100=0.47282884713052*x       - we divide both sides of the equation by (0.47282884713052) to get x
100/0.47282884713052=x
211.49301825994=x
x=211.49301825994

now we have:
19.69 is 211.49301825994% of 9.31
