What is 90 percent of 54047 - 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 54047 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 54047 is 100%, so we can write it down as 54047=100%.
4. We know, that x is 90% of the output value, so we can write it down as x=90%.
5. Now we have two simple equations:
1) 54047=100%
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:
54047/x=100%/90%
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for what is 90% of 54047

54047/x=100/90
(54047/x)*x=(100/90)*x       - we multiply both sides of the equation by x
54047=1.11111111111*x       - we divide both sides of the equation by (1.11111111111) to get x
54047/1.11111111111=x
48642.3=x
x=48642.3

now we have:
90% of 54047=48642.3
