7 is what percent of 1.429 - 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 1.429 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 1.429, so we can write it down as 100%=1.429.
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%=1.429
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%=1.429/7
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 1.429

100%/x%=1.429/7
(100/x)*x=(1.429/7)*x       - we multiply both sides of the equation by x
100=0.20414285714286*x       - we divide both sides of the equation by (0.20414285714286) to get x
100/0.20414285714286=x
489.85304408677=x
x=489.85304408677

now we have:
7 is 489.85304408677% of 1.429
