What is 3.07 percent of 678.75 - 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 678.75 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 678.75 is 100%, so we can write it down as 678.75=100%.
4. We know, that x is 3.07% of the output value, so we can write it down as x=3.07%.
5. Now we have two simple equations:
1) 678.75=100%
2) x=3.07%
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:
678.75/x=100%/3.07%
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 3.07% of 678.75

678.75/x=100/3.07
(678.75/x)*x=(100/3.07)*x       - we multiply both sides of the equation by x
678.75=32.57328990228*x       - we divide both sides of the equation by (32.57328990228) to get x
678.75/32.57328990228=x
20.837625=x
x=20.837625

now we have:
3.07% of 678.75=20.837625
