What is 2/18 plus 2/6? (Answer: 4/9)

Exact Answer

==================================================
Problem: What is 2/18 plus 2/6?
Formula / Expression: 2/18 + 2/6
Final Answer: 4/9
==================================================

Step-by-Step Solution:

Step 1: Find the Least Common Denominator (LCD)
Notice that 18 is an exact multiple of 6 (6 × 3 = 18). The Least Common Denominator (LCD) is simply 18, meaning we only need to scale one fraction.
Working: LCD(18, 6) = 18

Step 2: Convert to Equivalent Fractions with Common Denominator 18
Multiply the numerator and denominator of 2/18 by 1, and multiply the numerator and denominator of 2/6 by 3 so both fractions share the common base 18.
Working: 2 × 1/18 × 1 = 2/18 and 2 × 3/6 × 3 = 6/18

Step 3: Add the Numerators
Now add the numerators (2 + 6 = 8) and keep the common denominator 18 unchanged.
Working: 2 + 6/18 = 8/18

Step 4: Simplify the Fraction to Lowest Terms
Find the Greatest Common Divisor (GCD) of 8 and 18, which is 2. Divide both the numerator and denominator by 2.
Working: 8 ÷ 2/18 ÷ 2 = 4/9

Step 5: Decimal & Percentage Representation
Dividing the numerator 4 by denominator 9 produces a repeating decimal (approximately 0.444444, or 44.4444%).
Working: 4 ÷ 9 = 0.444444 (44.4444%)

Key Values:
- Simplified Fraction: 4/9
- Mixed Number Form: 4/9
- Decimal Value: 0.444444
- Percentage: 44.4444%
