55 is what percent of 4000009 - 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 4000009 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 4000009, so we can write it down as 100%=4000009.
4. We know, that x% equals 55 of the output value, so we can write it down as x%=55.
5. Now we have two simple equations:
1) 100%=4000009
2) x%=55
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%=4000009/55
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 55 is what percent of 4000009

100%/x%=4000009/55
(100/x)*x=(4000009/55)*x       - we multiply both sides of the equation by x
100=72727.436363636*x       - we divide both sides of the equation by (72727.436363636) to get x
100/72727.436363636=x
0.001374996906257=x
x=0.001374996906257

now we have:
55 is 0.001374996906257% of 4000009
