7 is what percent of 3330 - 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 3330 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 3330, so we can write it down as 100%=3330.
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%=3330
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%=3330/7
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 3330

100%/x%=3330/7
(100/x)*x=(3330/7)*x       - we multiply both sides of the equation by x
100=475.71428571429*x       - we divide both sides of the equation by (475.71428571429) to get x
100/475.71428571429=x
0.21021021021021=x
x=0.21021021021021

now we have:
7 is 0.21021021021021% of 3330
