27.8 is what percent of 169 - 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 169 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 169, so we can write it down as 100%=169.
4. We know, that x% equals 27.8 of the output value, so we can write it down as x%=27.8.
5. Now we have two simple equations:
1) 100%=169
2) x%=27.8
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%=169/27.8
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 27.8 is what percent of 169

100%/x%=169/27.8
(100/x)*x=(169/27.8)*x       - we multiply both sides of the equation by x
100=6.0791366906475*x       - we divide both sides of the equation by (6.0791366906475) to get x
100/6.0791366906475=x
16.449704142012=x
x=16.449704142012

now we have:
27.8 is 16.449704142012% of 169
