From the biconditional statement ` p harrq`, where.
(i) p: The units digits of an interger is zero.
q: It is divisble by 5.
(ii) p: A Natural number is odd.
q: Natyral number n is not divisible by 2.
(iii) p: A triangle is an equalateral triangle .
q: All the three sides of a triangle are equal.

Explanation

To solve the problem, we need to convert the given biconditional statements into conditional statements. A biconditional statement of the form \( p \iff q \) can be expressed as two conditional statements: \( p \implies q \) and \( q \implies p \).

Let's break down each part of the question step by step.

### (i)
**Given:**
- \( p \): The unit digit of an integer is zero.
- \( q \): It is divisible by 5.

**Biconditional Statement:**
\( p \iff q \)

**Step 1: Write the conditional statements.**
1. **If the unit digit of an integer is zero, then it is divisible by 5.**
- This is \( p \implies q \).
2. **If it is divisible by 5, then the unit digit of an integer is zero.**
- This is \( q \implies p \).

**Final Conditional Statements:**
- \( p \implies q \): If the unit digit of an integer is zero, then it is divisible by 5.
- \( q \implies p \): If it is divisible by 5, then the unit digit of an integer is zero.

### (ii)
**Given:**
- \( p \): A natural number is odd.
- \( q \): A natural number \( n \) is not divisible by 2.

**Biconditional Statement:**
\( p \iff q \)

**Step 1: Write the conditional statements.**
1. **If a natural number is odd, then it is not divisible by 2.**
- This is \( p \implies q \).
2. **If a natural number is not divisible by 2, then it is odd.**
- This is \( q \implies p \).

**Final Conditional Statements:**
- \( p \implies q \): If a natural number is odd, then it is not divisible by 2.
- \( q \implies p \): If a natural number is not divisible by 2, then it is odd.

### (iii)
**Given:**
- \( p \): A triangle is an equilateral triangle.
- \( q \): All three sides of a triangle are equal.

**Biconditional Statement:**
\( p \iff q \)

**Step 1: Write the conditional statements.**
1. **If a triangle is an equilateral triangle, then all three sides of the triangle are equal.**
- This is \( p \implies q \).
2. **If all three sides of a triangle are equal, then it is an equilateral triangle.**
- This is \( q \implies p \).

**Final Conditional Statements:**
- \( p \implies q \): If a triangle is an equilateral triangle, then all three sides of the triangle are equal.
- \( q \implies p \): If all three sides of a triangle are equal, then it is an equilateral triangle.

### Summary of Conditional Statements:
1. **For (i)**:
- \( p \implies q \): If the unit digit of an integer is zero, then it is divisible by 5.
- \( q \implies p \): If it is divisible by 5, then the unit digit of an integer is zero.

2. **For (ii)**:
- \( p \implies q \): If a natural number is odd, then it is not divisible by 2.
- \( q \implies p \): If a natural number is not divisible by 2, then it is odd.

3. **For (iii)**:
- \( p \implies q \): If a triangle is an equilateral triangle, then all three sides of the triangle are equal.
- \( q \implies p \): If all three sides of a triangle are equal, then it is an equilateral triangle.
