What is 80 percent of 123800 - 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 123800 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 123800 is 100%, so we can write it down as 123800=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) 123800=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:
123800/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 123800

123800/x=100/80
(123800/x)*x=(100/80)*x       - we multiply both sides of the equation by x
123800=1.25*x       - we divide both sides of the equation by (1.25) to get x
123800/1.25=x
99040=x
x=99040

now we have:
80% of 123800=99040
