What is 90 percent of 31948 - 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 31948 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 31948 is 100%, so we can write it down as 31948=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) 31948=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:
31948/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 31948

31948/x=100/90
(31948/x)*x=(100/90)*x       - we multiply both sides of the equation by x
31948=1.1111111111111*x       - we divide both sides of the equation by (1.1111111111111) to get x
31948/1.1111111111111=x
28753.2=x
x=28753.2

now we have:
90% of 31948=28753.2
