0.51 is what percent of 20000000 - 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 20000000 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 20000000, so we can write it down as 100%=20000000.
4. We know, that x% equals 0.51 of the output value, so we can write it down as x%=0.51.
5. Now we have two simple equations:
1) 100%=20000000
2) x%=0.51
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%=20000000/0.51
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 0.51 is what percent of 20000000

100%/x%=20000000/0.51
(100/x)*x=(20000000/0.51)*x       - we multiply both sides of the equation by x
100=39215686.27451*x       - we divide both sides of the equation by (39215686.27451) to get x
100/39215686.27451=x
2.55E-6=x
x=2.55E-6

now we have:
0.51 is 2.55E-6% of 20000000
