90 is what percent of 5555 - 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 5555 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 5555, so we can write it down as 100%=5555.
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%=5555
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%=5555/90
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 5555

100%/x%=5555/90
(100/x)*x=(5555/90)*x       - we multiply both sides of the equation by x
100=61.722222222222*x       - we divide both sides of the equation by (61.722222222222) to get x
100/61.722222222222=x
1.6201620162016=x
x=1.6201620162016

now we have:
90 is 1.6201620162016% of 5555
