Answer: 25/40

To find an equivalent fraction, you must multiply both the numerator and the denominator by the same non-zero number. For the correct answer, 5/8 is multiplied by 5/5: (5 × 5) / (8 × 5) = 25/40. The other options do not maintain this equivalency.

A carpenter has a piece of wood that is 10 1/2 feet long. He needs to cut a piece from it that is 3 2/3 feet long. After he cuts the piece, what is the length of the remaining wood?

Answer: 6 5/6 feet

To subtract the mixed numbers, first find a common denominator for the fractions, which is 6. Convert 10 1/2 to 10 3/6 and 3 2/3 to 3 4/6. Since 3/6 is smaller than 4/6, you need to borrow from the whole number. 10 3/6 becomes 9 + 1 + 3/6 = 9 9/6. Now subtract: 9 9/6 - 3 4/6 = 6 5/6 feet.
