19.77 is what percent of 18.69 - 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 18.69 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 18.69, so we can write it down as 100%=18.69.
4. We know, that x% equals 19.77 of the output value, so we can write it down as x%=19.77.
5. Now we have two simple equations:
1) 100%=18.69
2) x%=19.77
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%=18.69/19.77
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 19.77 is what percent of 18.69

100%/x%=18.69/19.77
(100/x)*x=(18.69/19.77)*x       - we multiply both sides of the equation by x
100=0.9453717754173*x       - we divide both sides of the equation by (0.9453717754173) to get x
100/0.9453717754173=x
105.77849117175=x
x=105.77849117175

now we have:
19.77 is 105.77849117175% of 18.69
