What is 4900000 percent of 7900000000 - 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 7900000000 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 7900000000 is 100%, so we can write it down as 7900000000=100%.
4. We know, that x is 4900000% of the output value, so we can write it down as x=4900000%.
5. Now we have two simple equations:
1) 7900000000=100%
2) x=4900000%
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:
7900000000/x=100%/4900000%
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 4900000% of 7900000000

7900000000/x=100/4900000
(7900000000/x)*x=(100/4900000)*x       - we multiply both sides of the equation by x
7900000000=2.0408163265306E-5*x       - we divide both sides of the equation by (2.0408163265306E-5) to get x
7900000000/2.0408163265306E-5=x
3.871E+14=x
x=3.871E+14

now we have:
4900000% of 7900000000=3.871E+14
