Here are the expanded notations for the numbers in question 1: 1. Write the following in expanded notation. a) For the number 1256: Step 1: Identify the place value of each digit. 1 is in the thousands place (1 × 1000). 2 is in the hundreds place (2 × 100). 5 is in the tens place (5 × 10). 6 is in the ones place (6 × 1). Step 2: Write the sum of the values of each digit. 1256 = 1000 + 200 + 50 + 6 The expanded notation is 1000 + 200 + 50 + 6 b) For the number 8105: Step 1: Identify the place value of each digit. 8 is in the thousands place (8 × 1000). 1 is in the hundreds place (1 × 100). 0 is in the tens place (0 × 10). 5 is in the ones place (5 × 1). Step 2: Write the sum of the values of each digit. 8105 = 8000 + 100 + 0 + 5 The expanded notation is 8000 + 100 + 5 c) For the number 5085: Step 1: Identify the place value of each digit. 5 is in the thousands place (5 × 1000). 0 is in the hundreds place (0 × 100). 8 is in the tens place (8 × 10). 5 is in the ones place (5 × 1). Step 2: Write the sum of the values of each digit. 5085 = 5000 + 0 + 80 + 5 The expanded notation is 5000 + 80 + 5 d) For the number 9450: Step 1: Identify the place value of each digit. 9 is in the thousands place (9 × 1000). 4 is in the hundreds place (4 × 100). 5 is in the tens place (5 × 10). 0 is in the ones place (0 × 1). Step 2: Write the sum of the values of each digit. 9450 = 9000 + 400 + 50 + 0 The expanded notation is 9000 + 400 + 50 e) For the number 6001: Step 1: Identify the place value of each digit. 6 is in the thousands place (6 × 1000). 0 is in the hundreds place (0 × 100). 0 is in the tens place (0 × 10). 1 is in the ones place (1 × 1). Step 2: Write the sum of the values of each digit. 6001 = 6000 + 0 + 0 + 1 The expanded notation is 6000 + 1 f) For the number 8020: Step 1: Identify the place value of each digit. 8 is in the thousands place (8 × 1000). 0 is in the hundreds place (0 × 100). 2 is in the tens place (2 × 10). 0 is in the ones place (0 × 1). Step 2: Write the sum of the values of each digit. 8020 = 8000 + 0 + 20 + 0 The expanded notation is 8000 + 20 For question 2, "Calculate the following", the examples provided (8000 + 100 + 7 = 8107 and 6000 + 200 + 80 + 5 = 6285) are already solved in the image.
