Here are the solutions to the questions: 1. The number shown by the arrow at (a) is... Step 1: Observe the number line. The major markings are 0, 1, 2, 3. Between any two consecutive integers (e.g., 2 and 3), there are 9 smaller divisions, meaning each segment represents 0.1. Step 2: Locate arrow (a). It is between 2 and 3. Counting down from 3, the first mark is 3 - 0.1 = 2.9. The second mark is 3 - 0.2 = 2.8. The number shown by arrow (a) is 2.8. The correct option is 2,8. 2. The number shown by the arrow at (b) is... Step 1: Locate arrow (b). It is between 0 and 1. As established, each small division represents 0.1. Step 2: Counting up from 0, the first mark is 0 + 0.1 = 0.1. The second is 0.2, the third is 0.3, and the fourth mark is 0 + 0.4 = 0.4. The number shown by arrow (b) is 0.4. The correct option is 0,4. 3. The number exactly halfway between 0,5 and 2 is ...... Step 1: To find the number exactly halfway between two numbers, calculate their average. The numbers are 0.5 and 2. Step 2: Apply the midpoint formula: Midpoint = Number 1 + Number 22 Midpoint = (0.5 + 2)/(2) Step 3: Perform the addition and division. Midpoint = (2.5)/(2) Midpoint = 1.25 The number exactly halfway between 0.5 and 2 is 1.25. The correct option is 1,25. Send me the next one 📸
