What is 78.421 percent of 4.25 - 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 4.25 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 4.25 is 100%, so we can write it down as 4.25=100%.
4. We know, that x is 78.421% of the output value, so we can write it down as x=78.421%.
5. Now we have two simple equations:
1) 4.25=100%
2) x=78.421%
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:
4.25/x=100%/78.421%
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 78.421% of 4.25

4.25/x=100/78.421
(4.25/x)*x=(100/78.421)*x       - we multiply both sides of the equation by x
4.25=1.2751686410528*x       - we divide both sides of the equation by (1.2751686410528) to get x
4.25/1.2751686410528=x
3.3328925=x
x=3.3328925

now we have:
78.421% of 4.25=3.3328925
