20.51 is what percent of 18.99 - 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 18.99 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 18.99, so we can write it down as 100%=18.99.
4. We know, that x% equals 20.51 of the output value, so we can write it down as x%=20.51.
5. Now we have two simple equations:
1) 100%=18.99
2) x%=20.51
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%=18.99/20.51
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 20.51 is what percent of 18.99

100%/x%=18.99/20.51
(100/x)*x=(18.99/20.51)*x       - we multiply both sides of the equation by x
100=0.92588980984885*x       - we divide both sides of the equation by (0.92588980984885) to get x
100/0.92588980984885=x
108.00421274355=x
x=108.00421274355

now we have:
20.51 is 108.00421274355% of 18.99
