Use a measurement interpretation: How many pieces of length foot fit into foot? Compute .
- (correct answer)
Explanation: This question tests dividing fractions using the reciprocal method (multiply by ), with a measurement interpretation of how many smaller lengths fit into a larger one. Compute . Verification: foot, matching the total. This means pieces of foot fit into foot, more than 2 full pieces. Common mistakes include dividing numerators and denominators separately to get as in choice D, or arithmetic errors like . Method: flip divisor, multiply, calculate, simplify if needed, verify. Visual: a number line from 0 to marked in increments shows segments.
