Exact Answer

==================================================
Problem: What is 2/8 plus 8/11?
Formula / Expression: 2/8 + 8/11
Final Answer: 43/44
==================================================

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 8/11 by 8 so both fractions share the common base 88.
Working: 2 × 11/8 × 11 = 22/88 and 8 × 8/11 × 8 = 64/88

Step 3: Add the Numerators
Now add the numerators (22 + 64 = 86) and keep the common denominator 88 unchanged.
Working: 22 + 64/88 = 86/88

Step 4: Simplify the Fraction to Lowest Terms
Find the Greatest Common Divisor (GCD) of 86 and 88, which is 2. Divide both the numerator and denominator by 2.
Working: 86 ÷ 2/88 ÷ 2 = 43/44

Step 5: Decimal & Percentage Representation
Dividing the numerator 43 by denominator 44 produces a repeating decimal (approximately 0.977273, or 97.7273%).
Working: 43 ÷ 44 = 0.977273 (97.7273%)

Key Values:
- Simplified Fraction: 43/44
- Mixed Number Form: 43/44
- Decimal Value: 0.977273
- Percentage: 97.7273%

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.

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 8/11 by 8 so both fractions share the common base 88.

2 × 11/8 × 11 = 22/88 and 8 × 8/11 × 8 = 64/88

Step 3

Add the Numerators

Now add the numerators (22 + 64 = 86) and keep the common denominator 88 unchanged.

22 + 64/88 = 86/88

Step 4

Simplify the Fraction to Lowest Terms
