What is 54.2 percent of 51 - 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 51 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 51 is 100%, so we can write it down as 51=100%.
4. We know, that x is 54.2% of the output value, so we can write it down as x=54.2%.
5. Now we have two simple equations:
1) 51=100%
2) x=54.2%
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:
51/x=100%/54.2%
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for what is 54.2% of 51

51/x=100/54.2
(51/x)*x=(100/54.2)*x       - we multiply both sides of the equation by x
51=1.8450184501845*x       - we divide both sides of the equation by (1.8450184501845) to get x
51/1.8450184501845=x
27.642=x
x=27.642

now we have:
54.2% of 51=27.642
