For any rational number \(\frac {a}{b} + 0 \), such that \(\text{b}\neq 0\), the value of \(\ \frac {a}{b} + 0 \) will be
1 \(\text{a}\)
2 \(\frac {a}{b}\)
3 \(\frac {b}{a}\)
4 \(\text{b}\)
Explanation:
\(\frac {a}{b}\) Solution: The sum of 0 and any rational number is the number itself. Thus, for any rational number \(\frac {a}{b}\)?, we have \(\frac {a}{b} + 0 = \frac {a}{b}?.\)

The predecessor of the smallest 3-digit number is:
1 999
2 100
3 101
4 99
Explanation:
99 Solution: Smallest three-digit number = 100 \(\therefore\) Predecessor of 100 = 100 - 1 = 99

Makthe correct alternative in the tollowing: If n is an odd natural number greater than 1, then the product of its successor and predecessor:
1 Is an odd natural number.
2 Is an even natural number.
3 Can be even or odd.
4 None of these.
Explanation:
Is an even natural number. Solution: The successor and predecessor of an odd natural number are both even. Here, n = odd. So Successor of n = n + 1 (Even natural number) Predecessor of n = n - 1 (Even natural number) Product = (n + 1) × (n - 1) = even × even = even Thus, the product of the successor and predecessor of n is an even number. Hence, the correct option is (b).

For any rational number \(\frac {a}{b} + 0 \), such that \(\text{b}\neq 0\), the value of \(\ \frac {a}{b} + 0 \) will be
1 \(\text{a}\)
2 \(\frac {a}{b}\)
3 \(\frac {b}{a}\)
4 \(\text{b}\)
Explanation:
\(\frac {a}{b}\) Solution: The sum of 0 and any rational number is the number itself. Thus, for any rational number \(\frac {a}{b}\)?, we have \(\frac {a}{b} + 0 = \frac {a}{b}?.\)
