What is 43 percent of 19.42 - 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 19.42 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 19.42 is 100%, so we can write it down as 19.42=100%.
4. We know, that x is 43% of the output value, so we can write it down as x=43%.
5. Now we have two simple equations:
1) 19.42=100%
2) x=43%
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:
19.42/x=100%/43%
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% of 19.42

19.42/x=100/43
(19.42/x)*x=(100/43)*x       - we multiply both sides of the equation by x
19.42=2.3255813953488*x       - we divide both sides of the equation by (2.3255813953488) to get x
19.42/2.3255813953488=x
8.3506=x
x=8.3506

now we have:
43% of 19.42=8.3506
