Explanation:

1. Place Value of Underlined Digits

2,487,492 (underlined digit: 4)

Step1: Identify the digit's position

The number is 2,487,492. Let's write the place values from right to left: ones, tens, hundreds, thousands, ten - thousands, hundred - thousands, millions. The underlined 4 is in the hundred - thousands place.

4,389,024 (underlined digit: 0)

Step1: Identify the digit's position

The number is 4,389,024. The underlined 0 is in the tens place.

2. Round 6,438,593 to the nearest 1,000

Step1: Identify the thousands place and the digit to the right

The number is 6,438,593. The thousands place digit is 8 (from 6,438,593), and the digit to the right (hundreds place) is 5.

Step2: Apply rounding rule

If the digit to the right of the place we are rounding to (thousands place) is 5 or more, we round up the thousands place digit. So we add 1 to the thousands place digit (8 + 1 = 9) and change all the digits to the right of the thousands place to 0. So 6,438,593 rounded to the nearest 1,000 is 6,439,000.

3. Population of Suwanee, Georgia

Step1: Set up the addition

Last year's population was 23,455, and the growth is 8,438. We need to find the sum: 23,455+8,438.

Step2: Perform the addition

23,455+8,438 = 31,893.

4. Find the product of 728×32

Step1: Use the distributive property (or long multiplication)

We can write 32 as 30 + 2. Then 728×32=728×(30 + 2)=728×30+728×2.

Step2: Calculate each part

728×30 = 21,840 and 728×2 = 1,456.

Step3: Add the results

21,840+1,456 = 23,296.

5. Find the quotient of 1,382÷4

Step1: Perform long division

4)1382

• 12 (4×300)

----
18

• 16 (4×40)

----
22

• 20 (4×5)

----
2
So 1,382÷4 = 345 with a remainder of 2, or as a decimal 345.5.

6. Josiah's toy cars

Step1: Perform division

Josiah has 147 toy cars and he organizes them in groups of 9. We need to find 147÷9.

Step2: Calculate the division

9×16 = 144, 147 - 144 = 3. So the final group will have 3 cars.

7. First 5 multiples

For 8:

Step1: Multiply 8 by 1,2,3,4,5

8×1 = 8, 8×2 = 16, 8×3 = 24, 8×4 = 32, 8×5 = 40. So the first 5 multiples of 8 are 8, 16, 24, 32, 40.

For 11:

Step1: Multiply 11 by 1,2,3,4,5

11×1 = 11, 11×2 = 22, 11×3 = 33, 11×4 = 44, 11×5 = 55. So the first 5 multiples of 11 are 11, 22, 33, 44, 55.

For 2:

Step1: Multiply 2 by 1,2,3,4,5

2×1 = 2, 2×2 = 4, 2×3 = 6, 2×4 = 8, 2×5 = 10. So the first 5 multiples of 2 are 2, 4, 6, 8, 10.

For 15:

Step1: Multiply 15 by 1,2,3,4,5

15×1 = 15, 15×2 = 30, 15×3 = 45, 15×4 = 60, 15×5 = 75. So the first 5 multiples of 15 are 15, 30, 45, 60, 75.

8. Factors of 15

Step1: Find numbers that divide 15 without remainder

15÷1 = 15, 15÷3 = 5, 15÷5 = 3, 15÷15 = 1. So the factors of 15 are 1, 3, 5, 15.
