15.51 is what percent of 223 - 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 223 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 223, so we can write it down as 100%=223.
4. We know, that x% equals 15.51 of the output value, so we can write it down as x%=15.51.
5. Now we have two simple equations:
1) 100%=223
2) x%=15.51
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%=223/15.51
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 15.51 is what percent of 223

100%/x%=223/15.51
(100/x)*x=(223/15.51)*x       - we multiply both sides of the equation by x
100=14.377820760799*x       - we divide both sides of the equation by (14.377820760799) to get x
100/14.377820760799=x
6.9551569506726=x
x=6.9551569506726

now we have:
15.51 is 6.9551569506726% of 223
