What is 27 percent of 124.2 - 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 124.2 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 124.2 is 100%, so we can write it down as 124.2=100%.
4. We know, that x is 27% of the output value, so we can write it down as x=27%.
5. Now we have two simple equations:
1) 124.2=100%
2) x=27%
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:
124.2/x=100%/27%
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 27% of 124.2

124.2/x=100/27
(124.2/x)*x=(100/27)*x       - we multiply both sides of the equation by x
124.2=3.7037037037037*x       - we divide both sides of the equation by (3.7037037037037) to get x
124.2/3.7037037037037=x
33.534=x
x=33.534

now we have:
27% of 124.2=33.534
