What is 6 percent of 78.5 - 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 78.5 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 78.5 is 100%, so we can write it down as 78.5=100%.
4. We know, that x is 6% of the output value, so we can write it down as x=6%.
5. Now we have two simple equations:
1) 78.5=100%
2) x=6%
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:
78.5/x=100%/6%
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 6% of 78.5

78.5/x=100/6
(78.5/x)*x=(100/6)*x       - we multiply both sides of the equation by x
78.5=16.666666666667*x       - we divide both sides of the equation by (16.666666666667) to get x
78.5/16.666666666667=x
4.71=x
x=4.71

now we have:
6% of 78.5=4.71
