Explanation:

Question 1: How is the square divided?

Step1: Observe the square

The square has 2 horizontal and 2 vertical lines (or is divided into 4 equal parts). So it's divided into 4 equal smaller squares (or 4 equal parts).

Step1: Identify the next digit

The digit after 8 (in tens place) is 2, which is less than 5.

Step2: Round down

So we keep 8 as it is and set the rest to 0. So $824 \approx 800$.

For 996 (underlined digit is 9, in tens place)

Step1: Identify the next digit

The digit after 9 (in ones place) is 6, which is greater than 5.

Step2: Round up

Adding 1 to 9 (tens place) makes it 10, so we carry over. The hundreds place 9 also becomes 10 when we carry over from tens, so we carry over again. So $996 \approx 1000$ (or more precisely, if we consider tens place, but since 99 + 1 = 100, so the number rounded to tens place is 1000? Wait, maybe the underlined digit is the second 9 (tens place). So number is 9 (hundreds), 9 (tens), 6 (ones). Rounding to tens place: look at ones digit (6 ≥ 5), so add 1 to tens place. 9 + 1 = 10, so carry over to hundreds place. Hundreds place 9 + 1 = 10, carry over to thousands place. So 996 rounded to tens place is 1000.

For 857 (underlined digit is 5, in tens place)

Answer:

Divided into 4 equal parts (or 4 equal squares)

Question 2: Round each number to the underlined place value.

For 824 (underlined digit is 8, in hundreds place)
