7 is what percent of 248 - 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 248 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 248, so we can write it down as 100%=248.
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%=248
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%=248/7
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 248

100%/x%=248/7
(100/x)*x=(248/7)*x       - we multiply both sides of the equation by x
100=35.4285714286*x       - we divide both sides of the equation by (35.4285714286) to get x
100/35.4285714286=x
2.82258064516=x
x=2.82258064516

now we have:
7 is 2.82258064516% of 248
