29.68 is what percent of 220 - 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 220 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 220, so we can write it down as 100%=220.
4. We know, that x% equals 29.68 of the output value, so we can write it down as x%=29.68.
5. Now we have two simple equations:
1) 100%=220
2) x%=29.68
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%=220/29.68
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 29.68 is what percent of 220

100%/x%=220/29.68
(100/x)*x=(220/29.68)*x       - we multiply both sides of the equation by x
100=7.4123989218329*x       - we divide both sides of the equation by (7.4123989218329) to get x
100/7.4123989218329=x
13.490909090909=x
x=13.490909090909

now we have:
29.68 is 13.490909090909% of 220
