What is 26.7 percent of 78.9 - 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 78.9 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 78.9 is 100%, so we can write it down as 78.9=100%.
4. We know, that x is 26.7% of the output value, so we can write it down as x=26.7%.
5. Now we have two simple equations:
1) 78.9=100%
2) x=26.7%
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:
78.9/x=100%/26.7%
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 26.7% of 78.9

78.9/x=100/26.7
(78.9/x)*x=(100/26.7)*x       - we multiply both sides of the equation by x
78.9=3.7453183520599*x       - we divide both sides of the equation by (3.7453183520599) to get x
78.9/3.7453183520599=x
21.0663=x
x=21.0663

now we have:
26.7% of 78.9=21.0663
