What is 57.7 percent of 280 - 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 280 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 280 is 100%, so we can write it down as 280=100%.
4. We know, that x is 57.7% of the output value, so we can write it down as x=57.7%.
5. Now we have two simple equations:
1) 280=100%
2) x=57.7%
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:
280/x=100%/57.7%
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 57.7% of 280

280/x=100/57.7
(280/x)*x=(100/57.7)*x       - we multiply both sides of the equation by x
280=1.7331022530329*x       - we divide both sides of the equation by (1.7331022530329) to get x
280/1.7331022530329=x
161.56=x
x=161.56

now we have:
57.7% of 280=161.56
