What is 2 percent of 687.38 - 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 687.38 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 687.38 is 100%, so we can write it down as 687.38=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) 687.38=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:
687.38/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 687.38

687.38/x=100/2
(687.38/x)*x=(100/2)*x       - we multiply both sides of the equation by x
687.38=50*x       - we divide both sides of the equation by (50) to get x
687.38/50=x
13.7476=x
x=13.7476

now we have:
2% of 687.38=13.7476
