19) The value of (3)/(2) × (1)/(2) ÷ (3)/(2) Step 1: Perform the multiplication from left to right. (3)/(2) × (1)/(2) = (3 × 1)/(2 × 2) = (3)/(4) Step 2: Perform the division. To divide by a fraction, multiply by its reciprocal. (3)/(4) ÷ (3)/(2) = (3)/(4) × (2)/(3) Step 3: Multiply the fractions. (3 × 2)/(4 × 3) = (6)/(12) Step 4: Simplify the fraction. (6)/(12) = (1)/(2) The options provided are A. 1, B. #, C. 100, D. 11, E. 12. None of the options match the calculated value of (1)/(2). The value is (1)/(2). 20) An aeroplane covers a distance of 300 Km in 5 hrs. Step 1: Recall the formula for average speed. Average Speed = DistanceTime Step 2: Substitute the given values into the formula. Distance = 300 Km Time = 5 hrs Average Speed = 300 Km5 hrs Step 3: Calculate the average speed. Average Speed = 60 Km/h Comparing this to the given options: A. 35 Km/h B. 40 Km/h C. 50 Km/h D. 60 Km/h E. 65 Km/h The calculated average speed matches option D. The average speed of the aeroplane is D. 60 Km/h. Send me the next one 📸
