Exact Answer

==================================================
Problem: What is 9/41 plus 2/9?
Formula / Expression: 9/41 + 2/9
Final Answer: 163/369
==================================================

Step-by-Step Solution:

Step 1: Find the Least Common Denominator (LCD)
The denominators 41 and 9 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 41 × 9 = 369.
Working: LCD(41, 9) = 369

Step 2: Convert to Equivalent Fractions with Common Denominator 369
Multiply the numerator and denominator of 9/41 by 9, and multiply the numerator and denominator of 2/9 by 41 so both fractions share the common base 369.
Working: 9 × 9/41 × 9 = 81/369 and 2 × 41/9 × 41 = 82/369

Step 3: Add the Numerators
Now add the numerators (81 + 82 = 163) and keep the common denominator 369 unchanged.
Working: 81 + 82/369 = 163/369

Step 4: Check if the Fraction Can Be Simplified
The Greatest Common Divisor (GCD) of 163 and 369 is 1, confirming that 163/369 cannot be reduced further—it is already in its simplest irreducible form.
Working: 163/369

Step 5: Decimal & Percentage Representation
Dividing the numerator 163 by denominator 369 produces a repeating decimal (approximately 0.441734, or 44.1734%).
Working: 163 ÷ 369 = 0.441734 (44.1734%)

Key Values:
- Simplified Fraction: 163/369
- Mixed Number Form: 163/369
