0.25 of the area of the land is 0.25 times the area of the land. You need to multiply 0.25 by 24.5 acres.
If you do it with pencil an paper, this is what it looks like.
24.5
x 0.25
-------------
1225
+ 490
------------
6125
Now you need to place the decimal point. 24.5 has one decimal place after the decimal point. 0.25 has 2 decimal places after the decimal point. 1 + 2 = 3. The answer must have 3 decimal places after the decimal point. Write 6125, and put your pencil tip right after the 5. Now count 3 places to the left, and place the decimal point between the 6 and the 1.
