7 is what percent of 3200000 - 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 3200000 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 3200000, so we can write it down as 100%=3200000.
4. We know, that x% equals 7 of the output value, so we can write it down as x%=7.
5. Now we have two simple equations:
1) 100%=3200000
2) x%=7
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%=3200000/7
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 7 is what percent of 3200000

100%/x%=3200000/7
(100/x)*x=(3200000/7)*x       - we multiply both sides of the equation by x
100=457142.85714286*x       - we divide both sides of the equation by (457142.85714286) to get x
100/457142.85714286=x
0.00021875=x
x=0.00021875

now we have:
7 is 0.00021875% of 3200000
