Exact Answer

==================================================
Problem: What is 2/8 plus 7/11?
Formula / Expression: 2/8 + 7/11
Final Answer: 39/44
==================================================

Step-by-Step Solution:

Step 1: Find the Least Common Denominator (LCD)
The denominators 8 and 11 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 8 × 11 = 88.
Working: LCD(8, 11) = 88

Step 2: Convert to Equivalent Fractions with Common Denominator 88
Multiply the numerator and denominator of 2/8 by 11, and multiply the numerator and denominator of 7/11 by 8 so both fractions share the common base 88.
Working: 2 × 11/8 × 11 = 22/88 and 7 × 8/11 × 8 = 56/88

Step 3: Add the Numerators
Now add the numerators (22 + 56 = 78) and keep the common denominator 88 unchanged.
Working: 22 + 56/88 = 78/88

Step 4: Simplify the Fraction to Lowest Terms
Find the Greatest Common Divisor (GCD) of 78 and 88, which is 2. Divide both the numerator and denominator by 2.
Working: 78 ÷ 2/88 ÷ 2 = 39/44

Step 5: Decimal & Percentage Representation
Dividing the numerator 39 by denominator 44 produces a repeating decimal (approximately 0.886364, or 88.6364%).
Working: 39 ÷ 44 = 0.886364 (88.6364%)

Key Values:
- Simplified Fraction: 39/44
- Mixed Number Form: 39/44
