Answer :
To solve these questions accurately, we'll break down each part and calculate where needed.
(a) The place value of 7 in 746328 is 700000.
- Place value depends on the position of the digit in the number. Here, 7 is in the hundred-thousands place, so its place value is $7 \times 100000 = 700000$.
(b) The successor of 96965 is 96966.
- The successor of a number is the number that comes directly after it, so we add 1 to 96965.
(c) The face value of 2 in 20638 is 2.
- Face value is the value of the digit itself, regardless of its position in the number.
(d) The predecessor of 136490 is 136489.
- The predecessor of a number is the number that comes directly before it, so we subtract 1 from 136490.
(e) $6000000 + 60000 + 600 + 6 = 6060606$.
- Simply add these numbers together to get the result.
(f) The predecessor of the smallest 7-digit number is 999999.
- The smallest 7-digit number is 1000000. The predecessor is the number before it, which is 999999.
(g) The successor of the smallest 6-digit number is 100001.
- The smallest 6-digit number is 100000. The successor is the next number, which is 100001.
(h) The predecessor of the greatest 7-digit number is 9999999.
- The greatest 7-digit number is 9999999. Its predecessor is 9999998.
(i) The successor of the greatest 5-digit number is 100000.
- The greatest 5-digit number is 99999. Adding 1 to this number gives us the smallest 6-digit number, which is 100000.
