Step-by-step explanation:
Step 1: Multiply the whole number part (1) by the denominator (8).
1 × 8 = 8
Step 2: Add the product from Step 1 (8) to the numerator (4).
8 + 4 = 12
Step 3: Write that result (12) above the denominator. So,
Step 4: The fraction
Can be reduced by dividing both numerator and denominator by the GCD(12,8) = 4. Thus,
