What is 71.5 percent of 900000 - 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 900000 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 900000 is 100%, so we can write it down as 900000=100%.
4. We know, that x is 71.5% of the output value, so we can write it down as x=71.5%.
5. Now we have two simple equations:
1) 900000=100%
2) x=71.5%
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:
900000/x=100%/71.5%
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 71.5% of 900000

900000/x=100/71.5
(900000/x)*x=(100/71.5)*x       - we multiply both sides of the equation by x
900000=1.3986013986014*x       - we divide both sides of the equation by (1.3986013986014) to get x
900000/1.3986013986014=x
643500=x
x=643500

now we have:
71.5% of 900000=643500
