42.9 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 42.9 of the output value, so we can write it down as x%=42.9.
5. Now we have two simple equations:
1) 100%=2.25
2) x%=42.9
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%=2.25/42.9
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 42.9 is what percent of 2.25

100%/x%=2.25/42.9
(100/x)*x=(2.25/42.9)*x       - we multiply both sides of the equation by x
100=0.052447552447552*x       - we divide both sides of the equation by (0.052447552447552) to get x
100/0.052447552447552=x
1906.6666666667=x
x=1906.6666666667

now we have:
42.9 is 1906.6666666667% of 2.25
