18.03 is what percent of 20.79 - 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 20.79 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 20.79, so we can write it down as 100%=20.79.
4. We know, that x% equals 18.03 of the output value, so we can write it down as x%=18.03.
5. Now we have two simple equations:
1) 100%=20.79
2) x%=18.03
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%=20.79/18.03
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 18.03 is what percent of 20.79

100%/x%=20.79/18.03
(100/x)*x=(20.79/18.03)*x       - we multiply both sides of the equation by x
100=1.153078202995*x       - we divide both sides of the equation by (1.153078202995) to get x
100/1.153078202995=x
86.724386724387=x
x=86.724386724387

now we have:
18.03 is 86.724386724387% of 20.79
