16.9 is what percent of 25.3 - 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 25.3 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 25.3, so we can write it down as 100%=25.3.
4. We know, that x% equals 16.9 of the output value, so we can write it down as x%=16.9.
5. Now we have two simple equations:
1) 100%=25.3
2) x%=16.9
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%=25.3/16.9
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 16.9 is what percent of 25.3

100%/x%=25.3/16.9
(100/x)*x=(25.3/16.9)*x       - we multiply both sides of the equation by x
100=1.4970414201183*x       - we divide both sides of the equation by (1.4970414201183) to get x
100/1.4970414201183=x
66.798418972332=x
x=66.798418972332

now we have:
16.9 is 66.798418972332% of 25.3
