What is 80 percent of 707.68 - 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 707.68 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 707.68 is 100%, so we can write it down as 707.68=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) 707.68=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:
707.68/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 707.68

707.68/x=100/80
(707.68/x)*x=(100/80)*x       - we multiply both sides of the equation by x
707.68=1.25*x       - we divide both sides of the equation by (1.25) to get x
707.68/1.25=x
566.144=x
x=566.144

now we have:
80% of 707.68=566.144
