What is 2/7 plus 4/11? (Answer: 50/77)

Exact Answer

==================================================
Problem: What is 2/7 plus 4/11?
Formula / Expression: 2/7 + 4/11
Final Answer: 50/77
==================================================

Step-by-Step Solution:

Step 1: Find the Least Common Denominator (LCD)
The denominators 7 and 11 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 7 × 11 = 77.
Working: LCD(7, 11) = 77

Step 2: Convert to Equivalent Fractions with Common Denominator 77
Multiply the numerator and denominator of 2/7 by 11, and multiply the numerator and denominator of 4/11 by 7 so both fractions share the common base 77.
Working: 2 × 11/7 × 11 = 22/77 and 4 × 7/11 × 7 = 28/77

Step 3: Add the Numerators
Now add the numerators (22 + 28 = 50) and keep the common denominator 77 unchanged.
Working: 22 + 28/77 = 50/77

Step 4: Check if the Fraction Can Be Simplified
The Greatest Common Divisor (GCD) of 50 and 77 is 1, confirming that 50/77 cannot be reduced further—it is already in its simplest irreducible form.
Working: 50/77

Step 5: Decimal & Percentage Representation
Dividing the numerator 50 by denominator 77 produces a repeating decimal (approximately 0.649351, or 64.9351%).
Working: 50 ÷ 77 = 0.649351 (64.9351%)

Key Values:
- Simplified Fraction: 50/77
- Mixed Number Form: 50/77
- Decimal Value: 0.649351
