What is 42.7 percent of 12 - 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 12 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 12 is 100%, so we can write it down as 12=100%.
4. We know, that x is 42.7% of the output value, so we can write it down as x=42.7%.
5. Now we have two simple equations:
1) 12=100%
2) x=42.7%
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:
12/x=100%/42.7%
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 42.7% of 12

12/x=100/42.7
(12/x)*x=(100/42.7)*x       - we multiply both sides of the equation by x
12=2.3419203747073*x       - we divide both sides of the equation by (2.3419203747073) to get x
12/2.3419203747073=x
5.124=x
x=5.124

now we have:
42.7% of 12=5.124
