What is 2 percent of 154.9 - 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 154.9 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 154.9 is 100%, so we can write it down as 154.9=100%.
4. We know, that x is 2% of the output value, so we can write it down as x=2%.
5. Now we have two simple equations:
1) 154.9=100%
2) x=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:
154.9/x=100%/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 2% of 154.9

154.9/x=100/2
(154.9/x)*x=(100/2)*x       - we multiply both sides of the equation by x
154.9=50*x       - we divide both sides of the equation by (50) to get x
154.9/50=x
3.098=x
x=3.098

now we have:
2% of 154.9=3.098
