45.1 is what percent of 450 - 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 450 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 450, so we can write it down as 100%=450.
4. We know, that x% equals 45.1 of the output value, so we can write it down as x%=45.1.
5. Now we have two simple equations:
1) 100%=450
2) x%=45.1
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%=450/45.1
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 45.1 is what percent of 450

100%/x%=450/45.1
(100/x)*x=(450/45.1)*x       - we multiply both sides of the equation by x
100=9.9778270509978*x       - we divide both sides of the equation by (9.9778270509978) to get x
100/9.9778270509978=x
10.022222222222=x
x=10.022222222222

now we have:
45.1 is 10.022222222222% of 450
