40 is what percent of 83000000 - 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 83000000 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 100% equals 83000000, so we can write it down as 100%=83000000.
4. We know, that x% equals 40 of the output value, so we can write it down as x%=40.
5. Now we have two simple equations:
1) 100%=83000000
2) x%=40
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:
100%/x%=83000000/40
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 40 is what percent of 83000000

100%/x%=83000000/40
(100/x)*x=(83000000/40)*x       - we multiply both sides of the equation by x
100=2075000*x       - we divide both sides of the equation by (2075000) to get x
100/2075000=x
4.8192771084337E-5=x
x=4.8192771084337E-5

now we have:
40 is 4.8192771084337E-5% of 83000000
