What is 1/12 plus 2/6? (Answer: 5/12)

Exact Answer

==================================================
Problem: What is 1/12 plus 2/6?
Formula / Expression: 1/12 + 2/6
Final Answer: 5/12
==================================================

Step-by-Step Solution:

Step 1: Find the Least Common Denominator (LCD)
Notice that 12 is an exact multiple of 6 (6 × 2 = 12). The Least Common Denominator (LCD) is simply 12, meaning we only need to scale one fraction.
Working: LCD(12, 6) = 12

Step 2: Convert to Equivalent Fractions with Common Denominator 12
Multiply the numerator and denominator of 1/12 by 1, and multiply the numerator and denominator of 2/6 by 2 so both fractions share the common base 12.
Working: 1 × 1/12 × 1 = 1/12 and 2 × 2/6 × 2 = 4/12

Step 3: Add the Numerators
Now add the numerators (1 + 4 = 5) and keep the common denominator 12 unchanged.
Working: 1 + 4/12 = 5/12

Step 4: Check if the Fraction Can Be Simplified
The Greatest Common Divisor (GCD) of 5 and 12 is 1, confirming that 5/12 cannot be reduced further—it is already in its simplest irreducible form.
Working: 5/12

Step 5: Decimal & Percentage Representation
Dividing the numerator 5 by denominator 12 produces a repeating decimal (approximately 0.416667, or 41.6667%).
Working: 5 ÷ 12 = 0.416667 (41.6667%)

Key Values:
- Simplified Fraction: 5/12
- Mixed Number Form: 5/12
- Decimal Value: 0.416667
- Percentage: 41.6667%
