Exact Answer

==================================================
Problem: What is 2/11 plus 3/9?
Formula / Expression: 2/11 + 3/9
Final Answer: 17/33
==================================================

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 3/9 by 11 so both fractions share the common base 99.
Working: 2 × 9/11 × 9 = 18/99 and 3 × 11/9 × 11 = 33/99

Step 3: Add the Numerators
Now add the numerators (18 + 33 = 51) and keep the common denominator 99 unchanged.
Working: 18 + 33/99 = 51/99

Step 4: Simplify the Fraction to Lowest Terms
Find the Greatest Common Divisor (GCD) of 51 and 99, which is 3. Divide both the numerator and denominator by 3.
Working: 51 ÷ 3/99 ÷ 3 = 17/33

Step 5: Decimal & Percentage Representation
Dividing the numerator 17 by denominator 33 produces a repeating decimal (approximately 0.515152, or 51.5152%).
Working: 17 ÷ 33 = 0.515152 (51.5152%)

Key Values:
- Simplified Fraction: 17/33
- Mixed Number Form: 17/33
- Decimal Value: 0.515152
- Percentage: 51.5152%

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 3/9 by 11 so both fractions share the common base 99.

2 × 9/11 × 9 = 18/99 and 3 × 11/9 × 11 = 33/99

Step 3

Add the Numerators

Now add the numerators (18 + 33 = 51) and keep the common denominator 99 unchanged.

18 + 33/99 = 51/99

Step 4

Simplify the Fraction to Lowest Terms

Find the Greatest Common Divisor (GCD) of 51 and 99, which is 3. Divide both the numerator and denominator by 3.

51 ÷ 3/99 ÷ 3 = 17/33
