Exact Answer

==================================================
Problem: What is 2/11 plus 2/8?
Formula / Expression: 2/11 + 2/8
Final Answer: 19/44
==================================================

Step-by-Step Solution:

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

Step 2: Convert to Equivalent Fractions with Common Denominator 88
Multiply the numerator and denominator of 2/11 by 8, and multiply the numerator and denominator of 2/8 by 11 so both fractions share the common base 88.
Working: 2 × 8/11 × 8 = 16/88 and 2 × 11/8 × 11 = 22/88

Step 3: Add the Numerators
Now add the numerators (16 + 22 = 38) and keep the common denominator 88 unchanged.
Working: 16 + 22/88 = 38/88

Step 4: Simplify the Fraction to Lowest Terms
Find the Greatest Common Divisor (GCD) of 38 and 88, which is 2. Divide both the numerator and denominator by 2.
Working: 38 ÷ 2/88 ÷ 2 = 19/44

Step 5: Decimal & Percentage Representation
Dividing the numerator 19 by denominator 44 produces a repeating decimal (approximately 0.431818, or 43.1818%).
Working: 19 ÷ 44 = 0.431818 (43.1818%)

Key Values:
- Simplified Fraction: 19/44
- Mixed Number Form: 19/44
- Decimal Value: 0.431818

Find the Least Common Denominator (LCD)

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

LCD(11, 8) = 88

Step 2

Convert to Equivalent Fractions with Common Denominator 88

Multiply the numerator and denominator of 2/11 by 8, and multiply the numerator and denominator of 2/8 by 11 so both fractions share the common base 88.

2 × 8/11 × 8 = 16/88 and 2 × 11/8 × 11 = 22/88

Step 3

Add the Numerators

Now add the numerators (16 + 22 = 38) and keep the common denominator 88 unchanged.

16 + 22/88 = 38/88

Step 4
