Exact Answer

==================================================
Problem: What is 9/29 plus 2/5?
Formula / Expression: 9/29 + 2/5
Final Answer: 103/145
==================================================

Step-by-Step Solution:

Step 1: Find the Least Common Denominator (LCD)
The denominators 29 and 5 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 29 × 5 = 145.
Working: LCD(29, 5) = 145

Step 2: Convert to Equivalent Fractions with Common Denominator 145
Multiply the numerator and denominator of 9/29 by 5, and multiply the numerator and denominator of 2/5 by 29 so both fractions share the common base 145.
Working: 9 × 5/29 × 5 = 45/145 and 2 × 29/5 × 29 = 58/145

Step 3: Add the Numerators
Now add the numerators (45 + 58 = 103) and keep the common denominator 145 unchanged.
Working: 45 + 58/145 = 103/145

Step 4: Check if the Fraction Can Be Simplified
The Greatest Common Divisor (GCD) of 103 and 145 is 1, confirming that 103/145 cannot be reduced further—it is already in its simplest irreducible form.
Working: 103/145

Step 5: Decimal & Percentage Representation
Dividing the numerator 103 by denominator 145 produces a repeating decimal (approximately 0.710345, or 71.0345%).
Working: 103 ÷ 145 = 0.710345 (71.0345%)

Key Values:
- Simplified Fraction: 103/145
- Mixed Number Form: 103/145
- Decimal Value: 0.710345
