What is 2/12 plus 1/2? (Answer: 2/3)

Exact Answer

==================================================
Problem: What is 2/12 plus 1/2?
Formula / Expression: 2/12 + 1/2
Final Answer: 2/3
==================================================

Step-by-Step Solution:

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

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

Step 3: Add the Numerators
Now add the numerators (2 + 6 = 8) and keep the common denominator 12 unchanged.
Working: 2 + 6/12 = 8/12

Step 4: Simplify the Fraction to Lowest Terms
Find the Greatest Common Divisor (GCD) of 8 and 12, which is 4. Divide both the numerator and denominator by 4.
Working: 8 ÷ 4/12 ÷ 4 = 2/3

Step 5: Decimal & Percentage Representation
Dividing the numerator 2 by denominator 3 produces a repeating decimal (approximately 0.666667, or 66.6667%).
Working: 2 ÷ 3 = 0.666667 (66.6667%)

Key Values:
- Simplified Fraction: 2/3
- Mixed Number Form: 2/3
- Decimal Value: 0.666667
- Percentage: 66.6667%
