29.1 is what percent of 45 - 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 45 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 45, so we can write it down as 100%=45.
4. We know, that x% equals 29.1 of the output value, so we can write it down as x%=29.1.
5. Now we have two simple equations:
1) 100%=45
2) x%=29.1
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%=45/29.1
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 29.1 is what percent of 45

100%/x%=45/29.1
(100/x)*x=(45/29.1)*x       - we multiply both sides of the equation by x
100=1.5463917525773*x       - we divide both sides of the equation by (1.5463917525773) to get x
100/1.5463917525773=x
64.666666666667=x
x=64.666666666667

now we have:
29.1 is 64.666666666667% of 45
