What is 25 percent of 29.81 - 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 29.81 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 29.81 is 100%, so we can write it down as 29.81=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) 29.81=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:
29.81/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 29.81

29.81/x=100/25
(29.81/x)*x=(100/25)*x       - we multiply both sides of the equation by x
29.81=4*x       - we divide both sides of the equation by (4) to get x
29.81/4=x
7.4525=x
x=7.4525

now we have:
25% of 29.81=7.4525
