What is 5/29 plus 2/3? (Answer: 73/87)

Exact Answer

==================================================
Problem: What is 5/29 plus 2/3?
Formula / Expression: 5/29 + 2/3
Final Answer: 73/87
==================================================

Step-by-Step Solution:

Step 1: Find the Least Common Denominator (LCD)
The denominators 29 and 3 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 29 × 3 = 87.
Working: LCD(29, 3) = 87

Step 2: Convert to Equivalent Fractions with Common Denominator 87
Multiply the numerator and denominator of 5/29 by 3, and multiply the numerator and denominator of 2/3 by 29 so both fractions share the common base 87.
Working: 5 × 3/29 × 3 = 15/87 and 2 × 29/3 × 29 = 58/87

Step 3: Add the Numerators
Now add the numerators (15 + 58 = 73) and keep the common denominator 87 unchanged.
Working: 15 + 58/87 = 73/87

Step 4: Check if the Fraction Can Be Simplified
The Greatest Common Divisor (GCD) of 73 and 87 is 1, confirming that 73/87 cannot be reduced further—it is already in its simplest irreducible form.
Working: 73/87

Step 5: Decimal & Percentage Representation
Dividing the numerator 73 by denominator 87 produces a repeating decimal (approximately 0.83908, or 83.908%).
Working: 73 ÷ 87 = 0.83908 (83.908%)

Key Values:
- Simplified Fraction: 73/87
- Mixed Number Form: 73/87
- Decimal Value: 0.83908
- Percentage: 83.908%
