The lightness or heaviness of somebody or thing is weight. 2. Units of weight are the gram and the (3) kilogram. 3. kilogram Write in kilograms and grams 4. 12.53 kg Step 1: Separate the whole number and decimal part. 12.53 kg = 12 kg + 0.53 kg Step 2: Convert the decimal part to grams (1 kg = 1000 g). 0.53 kg = 0.53 × 1000 g = 530 g Step 3: Combine the kilograms and grams. 12 kg 530 g 5. 5.76 kg Step 1: Separate the whole number and decimal part. 5.76 kg = 5 kg + 0.76 kg Step 2: Convert the decimal part to grams. 0.76 kg = 0.76 × 1000 g = 760 g Step 3: Combine the kilograms and grams. 5 kg 760 g 6. 3380 g Step 1: Separate the thousands from the hundreds/tens/units. 3380 g = 3000 g + 380 g Step 2: Convert grams to kilograms (1000 g = 1 kg). 3000 g = 3 kg Step 3: Combine the kilograms and grams. 3 kg 380 g 7. 7423 g Step 1: Separate the thousands from the hundreds/tens/units. 7423 g = 7000 g + 423 g Step 2: Convert grams to kilograms. 7000 g = 7 kg Step 3: Combine the kilograms and grams. 7 kg 423 g Word Problems 8. A man bought 200 bags of beans, each weighing 50kg. He sold 5000kg of the beans. His children were given 5 bags. How much rice did he have left? (Assuming "rice" is a typo and should be "beans"). Step 1: Calculate the total weight of beans bought. Total beans bought = 200 bags × 50 kg/bag = 10000 kg Step 2: Calculate the weight of beans given to children. Beans for children = 5 bags × 50 kg/bag = 250 kg Step 3: Calculate the total weight of beans used (sold + given away). Total beans used = 5000 kg + 250 kg = 5250 kg Step 4: Calculate the remaining beans. Beans left = 10000 kg - 5250 kg = 4750 kg 4750 kg 9. If Mr. James travels a distance of 28km in 4 hours on his bicycle. Find his average speed in kilometer per hour. Step 1: Recall the formula for average speed. Average Speed = DistanceTime Step 2: Substitute the given values. Average Speed = 28 km4 hours Step 3: Calculate the speed. Average Speed = 7 km/h 7 km/h 10. A tricycle travelled 270km in a time of 3 hours. Find the average speed. Step 1: Recall the formula for average speed. Average Speed = DistanceTime Step 2: Substitute the given values. Average Speed = 270 km3 hours Step 3: Calculate the speed. Average Speed = 90 km/h 90 km/h WEEK FOUR: QUANTITATIVE REASONING (TIMED, CONTD) No questions are visible in this section.
