7 is what percent of 2242 - 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 2242 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 2242, so we can write it down as 100%=2242.
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%=2242
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%=2242/7
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 2242

100%/x%=2242/7
(100/x)*x=(2242/7)*x       - we multiply both sides of the equation by x
100=320.28571428571*x       - we divide both sides of the equation by (320.28571428571) to get x
100/320.28571428571=x
0.31222123104371=x
x=0.31222123104371

now we have:
7 is 0.31222123104371% of 2242
