4.45 is what percent of 12.99 - 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 12.99 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 12.99, so we can write it down as 100%=12.99.
4. We know, that x% equals 4.45 of the output value, so we can write it down as x%=4.45.
5. Now we have two simple equations:
1) 100%=12.99
2) x%=4.45
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%=12.99/4.45
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 4.45 is what percent of 12.99

100%/x%=12.99/4.45
(100/x)*x=(12.99/4.45)*x       - we multiply both sides of the equation by x
100=2.9191011235955*x       - we divide both sides of the equation by (2.9191011235955) to get x
100/2.9191011235955=x
34.257120862202=x
x=34.257120862202

now we have:
4.45 is 34.257120862202% of 12.99
