Explanation:

Step1: Analyze the first sub - question (Determine place value of 8, \underline{4}89,321)

In the number 8,489,321, we start from the right and move left to identify place values. The places are: ones, tens, hundreds, thousands, ten - thousands, hundred - thousands, millions. The digit 4 is in the hundred - thousands place? Wait, no. Wait, let's count the positions. Let's write the number in terms of place values:

The number 8,489,321 can be broken down as: 8 (millions place) + 4×100,000 (hundred - thousands place) + 8×10,000 (ten - thousands place) + 9×1,000 (thousands place) + 3×100 (hundreds place) + 2×10 (tens place) + 1×1 (ones place). Wait, no, the underlined digit is 4. Let's count the digits from the right. The right - most digit is 1 (ones), then 2 (tens), 3 (hundreds), 9 (thousands), 8 (ten - thousands), 4 (hundred - thousands), 8 (millions). Wait, no, 8,489,321: the digits are 8 (million), 4 (hundred thousand), 8 (ten thousand), 9 (thousand), 3 (hundred), 2 (ten), 1 (one). So the underlined 4 is in the hundred - thousand place.

Step2: Analyze the second sub - question (876,\underline{5}43)

For the number 876,543, let's break down the place values. From right: 3 (ones), 4 (tens), 5 (hundreds), 6 (thousands), 7 (ten - thousands), 8 (hundred - thousands). Wait, no: 876,543 = 8×100,000 (hundred - thousands) + 7×10,000 (ten - thousands) + 6×1,000 (thousands) + 5×100 (hundreds) + 4×10 (tens) + 3×1 (ones). So the underlined 5 is in the hundred place.

Step3: Analyze the third sub - question (\underline{2},012,005)

For the number 2,012,005, the digits are 2 (million), 0 (hundred - thousand), 1 (ten - thousand), 2 (thousand), 0 (hundred), 0 (ten), 5 (one). So the underlined 2 is in the million place.

Step4: Write a number with 3 in ten - thousand place

The ten - thousand place is the 5th digit from the right (or 4th digit from the left if we consider from the first non - zero digit). For example, 30,000 is a number, but we can have more digits. Let's take 130,000. Here, the digit 3 is in the ten - thousand place (1 (hundred - thousand), 3 (ten - thousand), 0 (thousand), 0 (hundred), 0 (ten), 0 (one)).

Step5: Write a number with 7 in ten place

The ten place is the 2nd digit from the right. For example, 70 is a number, but we can have more digits. Let's take 170. Here, the digit 7 is in the ten place (1 (hundred), 7 (ten), 0 (one)).

Step6: Spell the numbers

• 10: Ten
• 20: Twenty
• 30: Thirty
• 40: Forty
• 50: Fifty
• 60: Sixty
• 70: Seventy
• 80: Eighty
• 90: Ninety
• 100: One Hundred

Answer:

s (for each sub - question):

1. Place value of 4 in 8, \underline{4}89,321: Hundred - thousand place.
2. Place value of 5 in 876,\underline{5}43: Hundred place.
3. Place value of 2 in \underline{2},012,005: Million place.
4. Number with 3 in ten - thousand place: 130,000 (or any number like 30,000, 230,000 etc.)
5. Number with 7 in ten place: 170 (or any number like 70, 270 etc.)
6. Spelling:

• 10: Ten
• 20: Twenty
• 30: Thirty
• 40: Forty
• 50: Fifty
• 60: Sixty
• 70: Seventy
• 80: Eighty
• 90: Ninety
• 100: One Hundred
