1.1 Step 1: Subtract the second number from the first. 3.5 - 1.4 = 2.1 Step 2: Subtract the third number from the result. 2.1 - 1.5 = 0.6 0.6 1.2 Step 1: Conversion factor: 1 m = 100 cm. 2.37 × 100 = 237 237 cm 1.3 Step 1: Conversion factor: 100 cm = 1 m. 250 ÷ 100 = 2.5 Step 2: Write to 2 decimal places. 2.5 = 2.50 2.50 m 1.4 Step 1: Distance formula: distance = speed × time. 50\ km/h × 1\ h = 50\ km 50 km 1.5 Step 1: Conversion factor: 1 kg = 1000 g. 2.75 × 1000 = 2750 2750 g 1.6 Step 1: Conversion factor: 1 tonne = 1000 kg. 3.20 × 1000 = 3200 Step 2: Write to 2 decimal places. 3200 = 3200.00 3200.00 kg 1.7 Step 1: 500 ml = 0.5 L (since 1000 ml = 1 L). Step 2: 1 L water weighs 1 kg. 0.5\ L × 1\ kg/L = 0.5\ kg 0.5 kg 1.8 Step 1: Cost formula: total cost = price per litre × number of litres. 1.20\ £/L × 25\ L = 30\ £ £30 1.9 Step 1: The scale is marked at 59 kg, 60 kg, 61 kg. Each division = 1 kg. Step 2: Car reading is 25% across the division from 60 kg to 61 kg. 0.25 × 1\ kg = 0.25\ kg Step 3: Add to starting mark. 60 + 0.25 = 60.25\ kg 60.25 kg
