90 is what percent of 9200 - 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 9200 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 9200, so we can write it down as 100%=9200.
4. We know, that x% equals 90 of the output value, so we can write it down as x%=90.
5. Now we have two simple equations:
1) 100%=9200
2) x%=90
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%=9200/90
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 90 is what percent of 9200

100%/x%=9200/90
(100/x)*x=(9200/90)*x       - we multiply both sides of the equation by x
100=102.22222222222*x       - we divide both sides of the equation by (102.22222222222) to get x
100/102.22222222222=x
0.97826086956522=x
x=0.97826086956522

now we have:
90 is 0.97826086956522% of 9200
