48 is what percent of 2.16 - 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 2.16 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 2.16, so we can write it down as 100%=2.16.
4. We know, that x% equals 48 of the output value, so we can write it down as x%=48.
5. Now we have two simple equations:
1) 100%=2.16
2) x%=48
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%=2.16/48
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 48 is what percent of 2.16

100%/x%=2.16/48
(100/x)*x=(2.16/48)*x       - we multiply both sides of the equation by x
100=0.045*x       - we divide both sides of the equation by (0.045) to get x
100/0.045=x
2222.2222222222=x
x=2222.2222222222

now we have:
48 is 2222.2222222222% of 2.16
