Question 1: Subtract \( 3\frac{1}{4} - 1\frac{2}{4} \).

Answer: 2

Question 2: Calculate \( 5\frac{3}{4} - 2\frac{1}{4} \).

Answer: 3\frac{1}{2}

Question 3: A recipe calls for \( 2\frac{2}{4} \) cups of sugar. If you have already added \( 1\frac{3}{4} \) cups, how much more do you need?

Answer: \( \frac{1}{2} \) cup

Question 4: Express \( 7\frac{4}{4} - 3\frac{3}{4} \) as an improper fraction and then subtract.

Answer: 4\frac{1}{4}

Question 5: Subtract \( 6\frac{5}{4} - 2\frac{6}{4} \).

Answer: 3\frac{2}{4} or 3\frac{1}{2}

Question 6: A cyclist covers \( 4\frac{1}{2} \) miles in the morning and \( 2\frac{2}{4} \) miles in the afternoon. How many miles did they cycle in total? Subtract the smaller from the larger to find the difference.

Answer: \( 2\frac{1}{4} \) miles

Question 7: Construct a triangle with sides measuring \( 3\frac{1}{2} \), \( 4\frac{2}{4} \), and \( 5\frac{1}{4} \).

Answer: Students draw and verify triangle side lengths on the grid.

Question 8: A container has \( 8\frac{3}{4} \) liters of juice. If \( 3\frac{1}{4} \) liters are used, how much remains?

Answer: 5\frac{1}{2} \) liters

Question 9: Calculate \( 9\frac{2}{4} - 4\frac{3}{4} \) and explain why the answer is a mixed number.

Answer: \( 4\frac{1}{2} \); because subtracting the whole numbers and fractions separately results in this mixed number.

Question 10: Identify and correct the mistake in subtracting \( 5\frac{2}{4} - 3\frac{3}{4} \) if a student incorrectly gets \( 1\frac{2}{4} \).

Answer: The student did not convert mixed numbers to improper fractions; they should convert to \( \frac{22}{4} \) and \( \frac{15}{4} \) before subtracting to get \( \frac{7}{4} = 1\frac{3}{4} \).
