Explanation:

Step1: Compare and order numbers in question 1

Compare 99, 985, 987. 99 has the fewest digits, so it's the smallest. Among 985 and 987, since 987 - 985=2, 987>985.

Step2: Order numbers in question 2

Compare 65,148, 7,986, 74,695. 7,986 has the fewest digits, so it's the smallest. Among 65,148 and 74,695, since 74695 - 65148 = 9547, 74,695>65,148.

Step3: Add symbol in question 3

876,548 and 877,548 have the same number of digits. Comparing from left - to - right, at the thousands place, 6 < 7, so 876,548<877,548.

Step4: Write number in question 4

784,965,120 = 784,965,120, so the number to fill is 784,965,120.

Step5: Order numbers in question 5

Compare 468,162,147, 468,163,147, 469,475. 469,475 has the fewest digits among them, so it's the smallest. Among 468,162,147 and 468,163,147, since 468163147 - 468162147=1000, 468,163,147>468,162,147.

Step6: Circle larger number in question 6

987,124,745 is a 9 - digit number and 1,000,000,000 is a 10 - digit number. So 1,000,000,000>987,124,745, circle 1,000,000,000.

Step7: Fill blanks in question 7

12,845 has the fewest digits, 102,625 and 102,634 have the same number of digits. Since 102634 - 102625 = 9, 12,845<102,625<102,634.

Step8: Add symbol in question 8

21,457,265 is a 7 - digit number and 21,586 is a 5 - digit number. So 21,457,265>21,586.

Step9: Order numbers in question 9

Compare 78,426, 78,500, 784,635. 784,635 is the largest as it has the most digits. Among 78,426 and 78,500, since 78500 - 78426 = 74, 784,635>78,500>78,426.

Step10: Fill blanks in question 10

42,628 has the fewest digits, 56,487 and 68,478 have the same number of digits. Since 68478 - 56487 = 11991, 42,628<56,487<68,478.

4. 784,965,120
5. 468,163,147 > 468,162,147 > 469,475
6. Circle 1,000,000,000
7. 12,845 < 102,625 < 102,634
8. 21,457,265 > 21,586
9. 784,635 > 78,500 > 78,426
10. 42,628 < 56,487 < 68,478
