161.5 is what percent of 228 - 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 228 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 228, so we can write it down as 100%=228.
4. We know, that x% equals 161.5 of the output value, so we can write it down as x%=161.5.
5. Now we have two simple equations:
1) 100%=228
2) x%=161.5
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%=228/161.5
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 161.5 is what percent of 228

100%/x%=228/161.5
(100/x)*x=(228/161.5)*x       - we multiply both sides of the equation by x
100=1.4117647058824*x       - we divide both sides of the equation by (1.4117647058824) to get x
100/1.4117647058824=x
70.833333333333=x
x=70.833333333333

now we have:
161.5 is 70.833333333333% of 228
