A) \( \frac{11}{12}=\frac{33}{36} \) B) \( \frac{7}{8}=\frac{35}{48} \) C) \( \frac{3}{9}=\frac{4}{12} \)

To determine whether the given fractions are equal, we can simplify or cross-multiply them. A) \( \frac{11}{12}=\frac{33}{36} \) Cross-multiplying: \( 11 \times 36 = 396 \) \( 12 \times 33 = 396 \) Since both products are equal, \( \frac{11}{12} = \frac{33}{36} \) is true. B) \( \frac{7}{8}=\frac{35}{48} \) Cross-multiplying: \( 7 \times 48 = 336 \) \( 8 \times 35 = 280 \) Since \( 336 \neq 280 \), \( \frac{7}{8} \neq \frac{35}{48} \) is false. C) \( \frac{3}{9}=\frac{4}{12} \) Simplifying both fractions: \( \frac{3}{9} = \frac{1}{3} \) \( \frac{4}{12} = \frac{1}{3} \) Since both simplified fractions are equal, \( \frac{3}{9} = \frac{4}{12} \) is true. In summary: A) True B) False C) True
