You are correct. My apologies for the error. Let's re-solve 4. a) with division. 4. a) Step 1: Rewrite the division of fractions as multiplication by the reciprocal of the second fraction. (3)/(5) ÷ (12)/(7) = (3)/(5) × (7)/(12) Step 2: Multiply the numerators and multiply the denominators. (3 × 7)/(5 × 12) = (21)/(60) Step 3: Simplify the fraction by dividing both the numerator and the denominator by their greatest common divisor. The greatest common divisor of 21 and 60 is 3. (21 ÷ 3)/(60 ÷ 3) = (7)/(20) The simplified expression is (7)/(20).
