alleryA rope of 5/6 m has 1/3 m cut off. How much is left?
A4/3
B1/2
C4/6 only
D2/3
Answer & Solution
Correct answer: B. 1/2
1. Subtraction needs a common denominator; change 1/3 to 2/6.
2. Subtract the numerators: 5 - 2 = 3, so 3/6, which reduces to 1/2.
3. 4/3 and 2/3 come from subtracting tops and bottoms wrongly; 4/6 miscounts the numerators.
