What is 1.23 percent of 40000 - 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 40000 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 40000 is 100%, so we can write it down as 40000=100%.
4. We know, that x is 1.23% of the output value, so we can write it down as x=1.23%.
5. Now we have two simple equations:
1) 40000=100%
2) x=1.23%
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:
40000/x=100%/1.23%
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 1.23% of 40000

40000/x=100/1.23
(40000/x)*x=(100/1.23)*x       - we multiply both sides of the equation by x
40000=81.30081300813*x       - we divide both sides of the equation by (81.30081300813) to get x
40000/81.30081300813=x
492=x
x=492

now we have:
1.23% of 40000=492
