What is 780000000 percent of 1600000 - 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 1600000 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 1600000 is 100%, so we can write it down as 1600000=100%.
4. We know, that x is 780000000% of the output value, so we can write it down as x=780000000%.
5. Now we have two simple equations:
1) 1600000=100%
2) x=780000000%
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:
1600000/x=100%/780000000%
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 780000000% of 1600000

1600000/x=100/780000000
(1600000/x)*x=(100/780000000)*x       - we multiply both sides of the equation by x
1600000=1.2820512820513E-7*x       - we divide both sides of the equation by (1.2820512820513E-7) to get x
1600000/1.2820512820513E-7=x
12480000000000=x
x=12480000000000

now we have:
780000000% of 1600000=12480000000000
