What is 3000 percent of 2.8 - 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 2.8 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 2.8 is 100%, so we can write it down as 2.8=100%.
4. We know, that x is 3000% of the output value, so we can write it down as x=3000%.
5. Now we have two simple equations:
1) 2.8=100%
2) x=3000%
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:
2.8/x=100%/3000%
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 3000% of 2.8

2.8/x=100/3000
(2.8/x)*x=(100/3000)*x       - we multiply both sides of the equation by x
2.8=0.033333333333333*x       - we divide both sides of the equation by (0.033333333333333) to get x
2.8/0.033333333333333=x
84=x
x=84

now we have:
3000% of 2.8=84
