1.8 is what percent of 8.73 - 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 8.73 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 8.73, so we can write it down as 100%=8.73.
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%=8.73
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%=8.73/1.8
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 8.73

100%/x%=8.73/1.8
(100/x)*x=(8.73/1.8)*x       - we multiply both sides of the equation by x
100=4.85*x       - we divide both sides of the equation by (4.85) to get x
100/4.85=x
20.618556701031=x
x=20.618556701031

now we have:
1.8 is 20.618556701031% of 8.73
