Exact Answer

==================================================
Problem: What is 2/8 plus 5/11?
Formula / Expression: 2/8 + 5/11
Final Answer: 31/44
==================================================

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 5/11 by 8 so both fractions share the common base 88.
Working: 2 × 11/8 × 11 = 22/88 and 5 × 8/11 × 8 = 40/88

Step 3: Add the Numerators
Now add the numerators (22 + 40 = 62) and keep the common denominator 88 unchanged.
Working: 22 + 40/88 = 62/88

Step 4: Simplify the Fraction to Lowest Terms
Find the Greatest Common Divisor (GCD) of 62 and 88, which is 2. Divide both the numerator and denominator by 2.
Working: 62 ÷ 2/88 ÷ 2 = 31/44

Step 5: Decimal & Percentage Representation
Dividing the numerator 31 by denominator 44 produces a repeating decimal (approximately 0.704545, or 70.4545%).
Working: 31 ÷ 44 = 0.704545 (70.4545%)

Key Values:
- Simplified Fraction: 31/44
- Mixed Number Form: 31/44
- Decimal Value: 0.704545
- Percentage: 70.4545%

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 5/11 by 8 so both fractions share the common base 88.

2 × 11/8 × 11 = 22/88 and 5 × 8/11 × 8 = 40/88

Step 3

Add the Numerators

Now add the numerators (22 + 40 = 62) and keep the common denominator 88 unchanged.

22 + 40/88 = 62/88

Step 4

Simplify the Fraction to Lowest Terms

Find the Greatest Common Divisor (GCD) of 62 and 88, which is 2. Divide both the numerator and denominator by 2.

62 ÷ 2/88 ÷ 2 = 31/44
