What is 42.8 percent of 281 - 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 281 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 281 is 100%, so we can write it down as 281=100%.
4. We know, that x is 42.8% of the output value, so we can write it down as x=42.8%.
5. Now we have two simple equations:
1) 281=100%
2) x=42.8%
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:
281/x=100%/42.8%
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 42.8% of 281

281/x=100/42.8
(281/x)*x=(100/42.8)*x       - we multiply both sides of the equation by x
281=2.3364485981308*x       - we divide both sides of the equation by (2.3364485981308) to get x
281/2.3364485981308=x
120.268=x
x=120.268

now we have:
42.8% of 281=120.268
