19.69 is what percent of 10 - 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 10 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 10, so we can write it down as 100%=10.
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%=10
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%=10/19.69
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 10

100%/x%=10/19.69
(100/x)*x=(10/19.69)*x       - we multiply both sides of the equation by x
100=0.5078720162519*x       - we divide both sides of the equation by (0.5078720162519) to get x
100/0.5078720162519=x
196.9=x
x=196.9

now we have:
19.69 is 196.9% of 10
