What is 7000000000 percent of 40000000 - 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 40000000 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 40000000 is 100%, so we can write it down as 40000000=100%.
4. We know, that x is 7000000000% of the output value, so we can write it down as x=7000000000%.
5. Now we have two simple equations:
1) 40000000=100%
2) x=7000000000%
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:
40000000/x=100%/7000000000%
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 7000000000% of 40000000

40000000/x=100/7000000000
(40000000/x)*x=(100/7000000000)*x       - we multiply both sides of the equation by x
40000000=1.4285714285714E-8*x       - we divide both sides of the equation by (1.4285714285714E-8) to get x
40000000/1.4285714285714E-8=x
2.8E+15=x
x=2.8E+15

now we have:
7000000000% of 40000000=2.8E+15
