What is 77.8 percent of 23.55 - 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 23.55 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 23.55 is 100%, so we can write it down as 23.55=100%.
4. We know, that x is 77.8% of the output value, so we can write it down as x=77.8%.
5. Now we have two simple equations:
1) 23.55=100%
2) x=77.8%
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:
23.55/x=100%/77.8%
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 77.8% of 23.55

23.55/x=100/77.8
(23.55/x)*x=(100/77.8)*x       - we multiply both sides of the equation by x
23.55=1.2853470437018*x       - we divide both sides of the equation by (1.2853470437018) to get x
23.55/1.2853470437018=x
18.3219=x
x=18.3219

now we have:
77.8% of 23.55=18.3219
