161.52 is what percent of 1620 - 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 1620 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 1620, so we can write it down as 100%=1620.
4. We know, that x% equals 161.52 of the output value, so we can write it down as x%=161.52.
5. Now we have two simple equations:
1) 100%=1620
2) x%=161.52
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%=1620/161.52
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 161.52 is what percent of 1620

100%/x%=1620/161.52
(100/x)*x=(1620/161.52)*x       - we multiply both sides of the equation by x
100=10.029717682021*x       - we divide both sides of the equation by (10.029717682021) to get x
100/10.029717682021=x
9.9703703703704=x
x=9.9703703703704

now we have:
161.52 is 9.9703703703704% of 1620
