What is 25 percent of 79.05 - 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 79.05 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 79.05 is 100%, so we can write it down as 79.05=100%.
4. We know, that x is 25% of the output value, so we can write it down as x=25%.
5. Now we have two simple equations:
1) 79.05=100%
2) x=25%
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:
79.05/x=100%/25%
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 25% of 79.05

79.05/x=100/25
(79.05/x)*x=(100/25)*x       - we multiply both sides of the equation by x
79.05=4*x       - we divide both sides of the equation by (4) to get x
79.05/4=x
19.7625=x
x=19.7625

now we have:
25% of 79.05=19.7625
