2.51 is what percent of 5.45 - 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 5.45 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 5.45, so we can write it down as 100%=5.45.
4. We know, that x% equals 2.51 of the output value, so we can write it down as x%=2.51.
5. Now we have two simple equations:
1) 100%=5.45
2) x%=2.51
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%=5.45/2.51
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 2.51 is what percent of 5.45

100%/x%=5.45/2.51
(100/x)*x=(5.45/2.51)*x       - we multiply both sides of the equation by x
100=2.1713147410359*x       - we divide both sides of the equation by (2.1713147410359) to get x
100/2.1713147410359=x
46.05504587156=x
x=46.05504587156

now we have:
2.51 is 46.05504587156% of 5.45
