What is 71.4 percent of 40.2 - 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 40.2 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 40.2 is 100%, so we can write it down as 40.2=100%.
4. We know, that x is 71.4% of the output value, so we can write it down as x=71.4%.
5. Now we have two simple equations:
1) 40.2=100%
2) x=71.4%
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:
40.2/x=100%/71.4%
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 71.4% of 40.2

40.2/x=100/71.4
(40.2/x)*x=(100/71.4)*x       - we multiply both sides of the equation by x
40.2=1.4005602240896*x       - we divide both sides of the equation by (1.4005602240896) to get x
40.2/1.4005602240896=x
28.7028=x
x=28.7028

now we have:
71.4% of 40.2=28.7028
