7 is what percent of 7040 - 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 7040 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 7040, so we can write it down as 100%=7040.
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%=7040
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%=7040/7
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 7040

100%/x%=7040/7
(100/x)*x=(7040/7)*x       - we multiply both sides of the equation by x
100=1005.7142857143*x       - we divide both sides of the equation by (1005.7142857143) to get x
100/1005.7142857143=x
0.099431818181818=x
x=0.099431818181818

now we have:
7 is 0.099431818181818% of 7040
