What is 4 percent of 124.7 - 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 124.7 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 124.7 is 100%, so we can write it down as 124.7=100%.
4. We know, that x is 4% of the output value, so we can write it down as x=4%.
5. Now we have two simple equations:
1) 124.7=100%
2) x=4%
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:
124.7/x=100%/4%
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 4% of 124.7

124.7/x=100/4
(124.7/x)*x=(100/4)*x       - we multiply both sides of the equation by x
124.7=25*x       - we divide both sides of the equation by (25) to get x
124.7/25=x
4.988=x
x=4.988

now we have:
4% of 124.7=4.988
