148.125

Answer 2

Answer:

12.3125

Step-by-step explanation:

We assume, that the number 49.25 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 49.25 is 100%, so we can write it down as 49.25=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) 49.25=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:

49.25/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 49.25

49.25/x=100/25

(49.25/x)*x=(100/25)*x - we multiply both sides of the equation by x

49.25=4*x - we divide both sides of the equation by (4) to get x

49.25/4=x

12.3125=x

x=12.3125

now we have:

25% of 49.25=12.3125
