17.7 is what percent of 69 - 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 69 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 69, so we can write it down as 100%=69.
4. We know, that x% equals 17.7 of the output value, so we can write it down as x%=17.7.
5. Now we have two simple equations:
1) 100%=69
2) x%=17.7
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%=69/17.7
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 17.7 is what percent of 69

100%/x%=69/17.7
(100/x)*x=(69/17.7)*x       - we multiply both sides of the equation by x
100=3.8983050847458*x       - we divide both sides of the equation by (3.8983050847458) to get x
100/3.8983050847458=x
25.652173913043=x
x=25.652173913043

now we have:
17.7 is 25.652173913043% of 69
