25.4 of 15% =

HELP IM STUCK ON THIS QESTION!!!

3.81

Step-by-step explanation:

1. We assume, that the number 25.4 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 25.4 is 100%, so we can write it down as 25.4=100%.

4. We know, that x is 15% of the output value, so we can write it down as x=15%.

5. Now we have two simple equations:

1) 25.4=100%

2) x=15%

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:

25.4/x=100%/15%

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 15% of 25.4

25.4/x=100/15

(25.4/x)*x=(100/15)*x       - we multiply both sides of the equation by x

25.4=6.66666666667*x       - we divide both sides of the equation by (6.66666666667) to get x

25.4/6.66666666667=x

3.81=x

x=3.81

answer: 800
