Exact Answer

==================================================
Problem: What is 2/9 plus 9/29?
Formula / Expression: 2/9 + 9/29
Final Answer: 139/261
==================================================

Step-by-Step Solution:

Step 1: Find the Least Common Denominator (LCD)
The denominators 9 and 29 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 9 × 29 = 261.
Working: LCD(9, 29) = 261

Step 2: Convert to Equivalent Fractions with Common Denominator 261
Multiply the numerator and denominator of 2/9 by 29, and multiply the numerator and denominator of 9/29 by 9 so both fractions share the common base 261.
Working: 2 × 29/9 × 29 = 58/261 and 9 × 9/29 × 9 = 81/261

Step 3: Add the Numerators
Now add the numerators (58 + 81 = 139) and keep the common denominator 261 unchanged.
Working: 58 + 81/261 = 139/261

Step 4: Check if the Fraction Can Be Simplified
The Greatest Common Divisor (GCD) of 139 and 261 is 1, confirming that 139/261 cannot be reduced further—it is already in its simplest irreducible form.
Working: 139/261

Step 5: Decimal & Percentage Representation
Dividing the numerator 139 by denominator 261 produces a repeating decimal (approximately 0.532567, or 53.2567%).
Working: 139 ÷ 261 = 0.532567 (53.2567%)

Key Values:
- Simplified Fraction: 139/261
- Mixed Number Form: 139/261
- Decimal Value: 0.532567
