What is 32.4 percent of 84 - 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 84 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 84 is 100%, so we can write it down as 84=100%.
4. We know, that x is 32.4% of the output value, so we can write it down as x=32.4%.
5. Now we have two simple equations:
1) 84=100%
2) x=32.4%
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:
84/x=100%/32.4%
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 32.4% of 84

84/x=100/32.4
(84/x)*x=(100/32.4)*x       - we multiply both sides of the equation by x
84=3.0864197530864*x       - we divide both sides of the equation by (3.0864197530864) to get x
84/3.0864197530864=x
27.216=x
x=27.216

now we have:
32.4% of 84=27.216
