What is 89000000000 percent of 51000000000 - 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 51000000000 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 51000000000 is 100%, so we can write it down as 51000000000=100%.
4. We know, that x is 89000000000% of the output value, so we can write it down as x=89000000000%.
5. Now we have two simple equations:
1) 51000000000=100%
2) x=89000000000%
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:
51000000000/x=100%/89000000000%
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 89000000000% of 51000000000

51000000000/x=100/89000000000
(51000000000/x)*x=(100/89000000000)*x       - we multiply both sides of the equation by x
51000000000=1.123595505618E-9*x       - we divide both sides of the equation by (1.123595505618E-9) to get x
51000000000/1.123595505618E-9=x
4.539E+19=x
x=4.539E+19

now we have:
89000000000% of 51000000000=4.539E+19
