What is 780000 percent of 2.5 - 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 2.5 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 2.5 is 100%, so we can write it down as 2.5=100%.
4. We know, that x is 780000% of the output value, so we can write it down as x=780000%.
5. Now we have two simple equations:
1) 2.5=100%
2) x=780000%
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:
2.5/x=100%/780000%
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 780000% of 2.5

2.5/x=100/780000
(2.5/x)*x=(100/780000)*x       - we multiply both sides of the equation by x
2.5=0.00012820512820513*x       - we divide both sides of the equation by (0.00012820512820513) to get x
2.5/0.00012820512820513=x
19500=x
x=19500

now we have:
780000% of 2.5=19500
