What is 71.2 percent of 43 - 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 43 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 43 is 100%, so we can write it down as 43=100%.
4. We know, that x is 71.2% of the output value, so we can write it down as x=71.2%.
5. Now we have two simple equations:
1) 43=100%
2) x=71.2%
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:
43/x=100%/71.2%
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 71.2% of 43

43/x=100/71.2
(43/x)*x=(100/71.2)*x       - we multiply both sides of the equation by x
43=1.4044943820225*x       - we divide both sides of the equation by (1.4044943820225) to get x
43/1.4044943820225=x
30.616=x
x=30.616

now we have:
71.2% of 43=30.616
