331 is what percent of 7 - 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 7 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 7, so we can write it down as 100%=7.
4. We know, that x% equals 331 of the output value, so we can write it down as x%=331.
5. Now we have two simple equations:
1) 100%=7
2) x%=331
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%=7/331
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 331 is what percent of 7

100%/x%=7/331
(100/x)*x=(7/331)*x       - we multiply both sides of the equation by x
100=0.021148036253776*x       - we divide both sides of the equation by (0.021148036253776) to get x
100/0.021148036253776=x
4728.5714285714=x
x=4728.5714285714

now we have:
331 is 4728.5714285714% of 7
