What is 4/29 plus 2/3? (Answer: 70/87)

Exact Answer

==================================================
Problem: What is 4/29 plus 2/3?
Formula / Expression: 4/29 + 2/3
Final Answer: 70/87
==================================================

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 4/29 by 3, and multiply the numerator and denominator of 2/3 by 29 so both fractions share the common base 87.
Working: 4 × 3/29 × 3 = 12/87 and 2 × 29/3 × 29 = 58/87

Step 3: Add the Numerators
Now add the numerators (12 + 58 = 70) and keep the common denominator 87 unchanged.
Working: 12 + 58/87 = 70/87

Step 4: Check if the Fraction Can Be Simplified
The Greatest Common Divisor (GCD) of 70 and 87 is 1, confirming that 70/87 cannot be reduced further—it is already in its simplest irreducible form.
Working: 70/87

Step 5: Decimal & Percentage Representation
Dividing the numerator 70 by denominator 87 produces a repeating decimal (approximately 0.804598, or 80.4598%).
Working: 70 ÷ 87 = 0.804598 (80.4598%)

Key Values:
- Simplified Fraction: 70/87
- Mixed Number Form: 70/87
- Decimal Value: 0.804598
