547.8 is what percent of 900 - 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 900 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 900, so we can write it down as 100%=900.
4. We know, that x% equals 547.8 of the output value, so we can write it down as x%=547.8.
5. Now we have two simple equations:
1) 100%=900
2) x%=547.8
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%=900/547.8
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 547.8 is what percent of 900

100%/x%=900/547.8
(100/x)*x=(900/547.8)*x       - we multiply both sides of the equation by x
100=1.6429353778751*x       - we divide both sides of the equation by (1.6429353778751) to get x
100/1.6429353778751=x
60.866666666667=x
x=60.866666666667

now we have:
547.8 is 60.866666666667% of 900
