What is 1.8 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 1.8% of the output value, so we can write it down as x=1.8%.
5. Now we have two simple equations:
1) 7900000000=100%
2) x=1.8%
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%/1.8%
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 1.8% of 7900000000

7900000000/x=100/1.8
(7900000000/x)*x=(100/1.8)*x       - we multiply both sides of the equation by x
7900000000=55.555555555556*x       - we divide both sides of the equation by (55.555555555556) to get x
7900000000/55.555555555556=x
142200000=x
x=142200000

now we have:
1.8% of 7900000000=142200000
