Exact Answer

==================================================
Problem: What is 2/11 plus 6/9?
Formula / Expression: 2/11 + 6/9
Final Answer: 28/33
==================================================

Step-by-Step Solution:

Step 1: Find the Least Common Denominator (LCD)
The denominators 11 and 9 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 11 × 9 = 99.
Working: LCD(11, 9) = 99

Step 2: Convert to Equivalent Fractions with Common Denominator 99
Multiply the numerator and denominator of 2/11 by 9, and multiply the numerator and denominator of 6/9 by 11 so both fractions share the common base 99.
Working: 2 × 9/11 × 9 = 18/99 and 6 × 11/9 × 11 = 66/99

Step 3: Add the Numerators
Now add the numerators (18 + 66 = 84) and keep the common denominator 99 unchanged.
Working: 18 + 66/99 = 84/99

Step 4: Simplify the Fraction to Lowest Terms
Find the Greatest Common Divisor (GCD) of 84 and 99, which is 3. Divide both the numerator and denominator by 3.
Working: 84 ÷ 3/99 ÷ 3 = 28/33

Step 5: Decimal & Percentage Representation
Dividing the numerator 28 by denominator 33 produces a repeating decimal (approximately 0.848485, or 84.8485%).
Working: 28 ÷ 33 = 0.848485 (84.8485%)

Key Values:
- Simplified Fraction: 28/33
- Mixed Number Form: 28/33
- Decimal Value: 0.848485

Find the Least Common Denominator (LCD)

The denominators 11 and 9 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 11 × 9 = 99.

LCD(11, 9) = 99

Step 2

Convert to Equivalent Fractions with Common Denominator 99

Multiply the numerator and denominator of 2/11 by 9, and multiply the numerator and denominator of 6/9 by 11 so both fractions share the common base 99.

2 × 9/11 × 9 = 18/99 and 6 × 11/9 × 11 = 66/99

Step 3

Add the Numerators

Now add the numerators (18 + 66 = 84) and keep the common denominator 99 unchanged.

18 + 66/99 = 84/99

Step 4
