13.45 is what percent of 145.5 - 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 145.5 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 145.5, so we can write it down as 100%=145.5.
4. We know, that x% equals 13.45 of the output value, so we can write it down as x%=13.45.
5. Now we have two simple equations:
1) 100%=145.5
2) x%=13.45
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%=145.5/13.45
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 13.45 is what percent of 145.5

100%/x%=145.5/13.45
(100/x)*x=(145.5/13.45)*x       - we multiply both sides of the equation by x
100=10.817843866171*x       - we divide both sides of the equation by (10.817843866171) to get x
100/10.817843866171=x
9.2439862542955=x
x=9.2439862542955

now we have:
13.45 is 9.2439862542955% of 145.5
