What is 2.7 percent of 6.4E+12 - 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 6.4E+12 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 6.4E+12 is 100%, so we can write it down as 6.4E+12=100%.
4. We know, that x is 2.7% of the output value, so we can write it down as x=2.7%.
5. Now we have two simple equations:
1) 6.4E+12=100%
2) x=2.7%
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:
6.4E+12/x=100%/2.7%
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 2.7% of 6.4E+12

6.4E+12/x=100/2.7
(6.4E+12/x)*x=(100/2.7)*x       - we multiply both sides of the equation by x
6.4E+12=37.037037037*x       - we divide both sides of the equation by (37.037037037) to get x
6.4E+12/37.037037037=x
172800000000=x
x=172800000000

now we have:
2.7% of 6.4E+12=172800000000
