What is 57.1 percent of 75 - 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 75 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 75 is 100%, so we can write it down as 75=100%.
4. We know, that x is 57.1% of the output value, so we can write it down as x=57.1%.
5. Now we have two simple equations:
1) 75=100%
2) x=57.1%
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:
75/x=100%/57.1%
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 57.1% of 75

75/x=100/57.1
(75/x)*x=(100/57.1)*x       - we multiply both sides of the equation by x
75=1.7513134851138*x       - we divide both sides of the equation by (1.7513134851138) to get x
75/1.7513134851138=x
42.825=x
x=42.825

now we have:
57.1% of 75=42.825
