What is 90000 percent of 75000000000 - 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 75000000000 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 75000000000 is 100%, so we can write it down as 75000000000=100%.
4. We know, that x is 90000% of the output value, so we can write it down as x=90000%.
5. Now we have two simple equations:
1) 75000000000=100%
2) x=90000%
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:
75000000000/x=100%/90000%
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 90000% of 75000000000

75000000000/x=100/90000
(75000000000/x)*x=(100/90000)*x       - we multiply both sides of the equation by x
75000000000=0.0011111111111111*x       - we divide both sides of the equation by (0.0011111111111111) to get x
75000000000/0.0011111111111111=x
67500000000000=x
x=67500000000000

now we have:
90000% of 75000000000=67500000000000
