C. Write the predecessor of each number.
1. 14, 32, 121
2. 69, 05, 070
3. 17, 86, 00, 506

D. Write the successor of each number.
1. 42
2. 57
3. 108

To solve this problem, we need to understand two key concepts: the predecessor and the successor of a number.
C. Write the predecessor of each number.
The predecessor of a number is the number that comes just before it. In other words, it is one less than the given number.

For the number 14 , the predecessor is 14 − 1 = 13 .

For the number 32 , the predecessor is 32 − 1 = 31 .

For the number 1212 , the predecessor is 1212 − 1 = 1211 .

For the number 69 , the predecessor is 69 − 1 = 68 .

For the number 05 (also written as 5 ), the predecessor is 5 − 1 = 4 .

For the number 070 (also written as 70 ), the predecessor is 70 − 1 = 69 .

For the number 17 , the predecessor is 17 − 1 = 16 .

For the number 86 , the predecessor is 86 − 1 = 85 .

For the number 00 (also written as 0 ), the predecessor is 0 − 1 = − 1 .

For the number 506 , the predecessor is 506 − 1 = 505 .


D. Write the successor of each number.
The successor of a number is the number that comes just after it. In other words, it is one more than the given number.

For the number 42 , the successor is 42 + 1 = 43 .

For the number 57 , the successor is 57 + 1 = 58 .

For the number 108 , the successor is 108 + 1 = 109 .


I hope this helps! Understanding predecessors and successors is a fundamental concept in mathematics that helps in learning to count, order, and compare numbers.
