29.9 is what percent of 663 - 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 663 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 663, so we can write it down as 100%=663.
4. We know, that x% equals 29.9 of the output value, so we can write it down as x%=29.9.
5. Now we have two simple equations:
1) 100%=663
2) x%=29.9
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%=663/29.9
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 29.9 is what percent of 663

100%/x%=663/29.9
(100/x)*x=(663/29.9)*x       - we multiply both sides of the equation by x
100=22.173913043478*x       - we divide both sides of the equation by (22.173913043478) to get x
100/22.173913043478=x
4.5098039215686=x
x=4.5098039215686

now we have:
29.9 is 4.5098039215686% of 663
