1.8 is what percent of 20.75 - 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 20.75 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 20.75, so we can write it down as 100%=20.75.
4. We know, that x% equals 1.8 of the output value, so we can write it down as x%=1.8.
5. Now we have two simple equations:
1) 100%=20.75
2) x%=1.8
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%=20.75/1.8
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 1.8 is what percent of 20.75

100%/x%=20.75/1.8
(100/x)*x=(20.75/1.8)*x       - we multiply both sides of the equation by x
100=11.527777777778*x       - we divide both sides of the equation by (11.527777777778) to get x
100/11.527777777778=x
8.6746987951807=x
x=8.6746987951807

now we have:
1.8 is 8.6746987951807% of 20.75
