What is 27 percent of 8.4 - 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 8.4 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 8.4 is 100%, so we can write it down as 8.4=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) 8.4=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:
8.4/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 8.4

8.4/x=100/27
(8.4/x)*x=(100/27)*x       - we multiply both sides of the equation by x
8.4=3.7037037037037*x       - we divide both sides of the equation by (3.7037037037037) to get x
8.4/3.7037037037037=x
2.268=x
x=2.268

now we have:
27% of 8.4=2.268
