What is 13.333333333333 percent of 77 - 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 77 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 77 is 100%, so we can write it down as 77=100%.
4. We know, that x is 13.333333333333% of the output value, so we can write it down as x=13.333333333333%.
5. Now we have two simple equations:
1) 77=100%
2) x=13.333333333333%
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:
77/x=100%/13.333333333333%
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 13.333333333333% of 77

77/x=100/13.333333333333
(77/x)*x=(100/13.333333333333)*x       - we multiply both sides of the equation by x
77=7.5*x       - we divide both sides of the equation by (7.5) to get x
77/7.5=x
10.266666666667=x
x=10.266666666667

now we have:
13.333333333333% of 77=10.266666666667
