28.91 is what percent of 2.25 - 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 2.25 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 2.25, so we can write it down as 100%=2.25.
4. We know, that x% equals 28.91 of the output value, so we can write it down as x%=28.91.
5. Now we have two simple equations:
1) 100%=2.25
2) x%=28.91
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%=2.25/28.91
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 28.91 is what percent of 2.25

100%/x%=2.25/28.91
(100/x)*x=(2.25/28.91)*x       - we multiply both sides of the equation by x
100=0.077827741265998*x       - we divide both sides of the equation by (0.077827741265998) to get x
100/0.077827741265998=x
1284.8888888889=x
x=1284.8888888889

now we have:
28.91 is 1284.8888888889% of 2.25
