What is 77.63 percent of 80 - 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 80 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 80 is 100%, so we can write it down as 80=100%.
4. We know, that x is 77.63% of the output value, so we can write it down as x=77.63%.
5. Now we have two simple equations:
1) 80=100%
2) x=77.63%
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:
80/x=100%/77.63%
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 77.63% of 80

80/x=100/77.63
(80/x)*x=(100/77.63)*x       - we multiply both sides of the equation by x
80=1.2881617931212*x       - we divide both sides of the equation by (1.2881617931212) to get x
80/1.2881617931212=x
62.104=x
x=62.104

now we have:
77.63% of 80=62.104
