9 is what percent of 547 - 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 547 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 547, so we can write it down as 100%=547.
4. We know, that x% equals 9 of the output value, so we can write it down as x%=9.
5. Now we have two simple equations:
1) 100%=547
2) x%=9
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%=547/9
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 9 is what percent of 547

100%/x%=547/9
(100/x)*x=(547/9)*x       - we multiply both sides of the equation by x
100=60.777777777778*x       - we divide both sides of the equation by (60.777777777778) to get x
100/60.777777777778=x
1.6453382084095=x
x=1.6453382084095

now we have:
9 is 1.6453382084095% of 547
