What is 87 percent of 11000000000 - 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 11000000000 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 11000000000 is 100%, so we can write it down as 11000000000=100%.
4. We know, that x is 87% of the output value, so we can write it down as x=87%.
5. Now we have two simple equations:
1) 11000000000=100%
2) x=87%
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:
11000000000/x=100%/87%
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 87% of 11000000000

11000000000/x=100/87
(11000000000/x)*x=(100/87)*x       - we multiply both sides of the equation by x
11000000000=1.1494252873563*x       - we divide both sides of the equation by (1.1494252873563) to get x
11000000000/1.1494252873563=x
9570000000=x
x=9570000000

now we have:
87% of 11000000000=9570000000
