What is 80 percent of 71820 - 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 71820 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 71820 is 100%, so we can write it down as 71820=100%.
4. We know, that x is 80% of the output value, so we can write it down as x=80%.
5. Now we have two simple equations:
1) 71820=100%
2) x=80%
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:
71820/x=100%/80%
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 80% of 71820

71820/x=100/80
(71820/x)*x=(100/80)*x       - we multiply both sides of the equation by x
71820=1.25*x       - we divide both sides of the equation by (1.25) to get x
71820/1.25=x
57456=x
x=57456

now we have:
80% of 71820=57456
