What is 55000000 percent of 7800000000 - 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 7800000000 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 7800000000 is 100%, so we can write it down as 7800000000=100%.
4. We know, that x is 55000000% of the output value, so we can write it down as x=55000000%.
5. Now we have two simple equations:
1) 7800000000=100%
2) x=55000000%
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:
7800000000/x=100%/55000000%
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 55000000% of 7800000000

7800000000/x=100/55000000
(7800000000/x)*x=(100/55000000)*x       - we multiply both sides of the equation by x
7800000000=1.8181818181818E-6*x       - we divide both sides of the equation by (1.8181818181818E-6) to get x
7800000000/1.8181818181818E-6=x
4.29E+15=x
x=4.29E+15

now we have:
55000000% of 7800000000=4.29E+15
