What is 43.4 percent of 47 - 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 47 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 47 is 100%, so we can write it down as 47=100%.
4. We know, that x is 43.4% of the output value, so we can write it down as x=43.4%.
5. Now we have two simple equations:
1) 47=100%
2) x=43.4%
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:
47/x=100%/43.4%
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 43.4% of 47

47/x=100/43.4
(47/x)*x=(100/43.4)*x       - we multiply both sides of the equation by x
47=2.3041474654378*x       - we divide both sides of the equation by (2.3041474654378) to get x
47/2.3041474654378=x
20.398=x
x=20.398

now we have:
43.4% of 47=20.398
