A tree is 25 7/12 feet high. Richard cuts off the top 8 7/8 feet. How tall is the tree now?
17 17/24 feet
16 17/24
17 7/24 feet
16 7/24 feet
16 17/24 feet
To find the height of the tree after cutting off the top, subtract 8 7/8 feet from the original height of 25 7/12 feet:
25 7/12 - 8 7/8
Convert both fractions to twelfths to make it easier to subtract:
25 7/12 = 25 14/24
8 7/8 = 8 18/24
Subtract 18/24 from 14/24:
14/24 - 18/24 = -4/24 = -1/6
Subtract 8 from 25:
25 - 8 = 17
So the new height of the tree is 17 - 1/6 feet, which is equal to 16 17/24 feet.
