161.5 is what percent of 225 - 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 225 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 225, so we can write it down as 100%=225.
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%=225
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%=225/161.5
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 225

100%/x%=225/161.5
(100/x)*x=(225/161.5)*x       - we multiply both sides of the equation by x
100=1.3931888544892*x       - we divide both sides of the equation by (1.3931888544892) to get x
100/1.3931888544892=x
71.777777777778=x
x=71.777777777778

now we have:
161.5 is 71.777777777778% of 225
