Question 1: Subtract \(rac{1}{3} - \frac{1}{4}\):

Answer: 1/12

Question 2: Calculate \(rac{2}{5} - \frac{1}{10}\) and simplify the result.

Answer: 3/10

Question 3: A student subtracts \(rac{2}{3} - \frac{1}{4}\) and gets \(rac{1}{12}\). Identify one mistake they might have made.

Answer: They may have incorrectly found a common denominator or subtracted numerators directly without common denominator.

Question 4: Subtract \(rac{3}{8} - \frac{1}{4}\), showing your working.

Answer: 3/8 - 2/8 = 1/8

Question 5: In subtracting \(rac{5}{6} - \frac{1}{2}\), a student gets \(rac{4}{12}\). What is the correct answer?

Answer: 1/3

Question 6: Construct a subtraction problem involving \(rac{3}{4}\) and \(rac{1}{2}\) and solve it.

Answer: 3/4 - 1/2 = 1/4

Question 7: Identify the error in this calculation: \(rac{2}{3} - \frac{1}{4} = \frac{1}{7}\).

Answer: Incorrect common denominator or addition/subtraction of numerators without proper denominator.

Question 8: Subtract \(rac{7}{10} - \frac{2}{5}\) and explain the steps you took.

Answer: 7/10 - 4/10 = 3/10

Question 9: A real-world scenario: If you have \(rac{4}{5}\) of a pizza and eat \(rac{1}{2}\) of what you have, how much pizza remains?

Answer: Remaining pizza = 4/5 - (1/2 of 4/5) = 4/5 - 2/5 = 2/5

Question 10: A challenge: Subtract \(rac{7}{8} - \frac{3}{4}\) and verify your result.

Answer: 7/8 - 6/8 = 1/8

Question 11: Find the error in this solution: \(rac{3}{7} - \frac{2}{3} = \frac{1}{10}\).

Answer: Incorrect common denominator or miscalculation in subtraction.
