1234567890 is what percent of 1 - 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 1 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 1, so we can write it down as 100%=1.
4. We know, that x% equals 1234567890 of the output value, so we can write it down as x%=1234567890.
5. Now we have two simple equations:
1) 100%=1
2) x%=1234567890
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%=1/1234567890
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 1234567890 is what percent of 1

100%/x%=1/1234567890
(100/x)*x=(1/1234567890)*x       - we multiply both sides of the equation by x
100=8.10000007371E-10*x       - we divide both sides of the equation by (8.10000007371E-10) to get x
100/8.10000007371E-10=x
123456789000=x
x=123456789000

now we have:
1234567890 is 123456789000% of 1
