Step 1: Determine the value of each minor division on the scales. Each major division (e.g., from 0 g to 200 g) is divided into 5 smaller segments by 4 minor marks. Therefore, the value of each minor division is 200 g5 = 40 g. Step 2: Read the mass on Scale A and convert units. The pointer on Scale A is at the 900 g mark. a) Mass in grams: 900 g b) Mass in kilograms: 900 g × 1 kg1000 g = 0.9 kg Mass on Scale A: a) 900 g, b) 0.9 kg Step 3: Read the mass on Scale B and convert units. The pointer on Scale B is two minor divisions past 400 g. a) Mass in grams: 400 g + (2 × 40 g) = 400 g + 80 g = 480 g b) Mass in kilograms: 480 g × 1 kg1000 g = 0.48 kg Mass on Scale B: a) 480 g, b) 0.48 kg Step 4: Read the mass on Scale C and convert units. The pointer on Scale C is three minor divisions past 1 kg (which is 1000 g). a) Mass in grams: 1000 g + (3 × 40 g) = 1000 g + 120 g = 1120 g b) Mass in kilograms: 1120 g × 1 kg1000 g = 1.12 kg Mass on Scale C: a) 1120 g, b) 1.12 kg That's 2 down. 3 left today — send the next one.
