7 is what percent of 1415 - 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 1415 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 1415, so we can write it down as 100%=1415.
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%=1415
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%=1415/7
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 1415

100%/x%=1415/7
(100/x)*x=(1415/7)*x       - we multiply both sides of the equation by x
100=202.14285714286*x       - we divide both sides of the equation by (202.14285714286) to get x
100/202.14285714286=x
0.49469964664311=x
x=0.49469964664311

now we have:
7 is 0.49469964664311% of 1415
