Exact Answer

==================================================
Problem: What is 2/6 plus 6/13?
Formula / Expression: 2/6 + 6/13
Final Answer: 31/39
==================================================

Step-by-Step Solution:

Step 1: Find the Least Common Denominator (LCD)
The denominators 6 and 13 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 6 × 13 = 78.
Working: LCD(6, 13) = 78

Step 2: Convert to Equivalent Fractions with Common Denominator 78
Multiply the numerator and denominator of 2/6 by 13, and multiply the numerator and denominator of 6/13 by 6 so both fractions share the common base 78.
Working: 2 × 13/6 × 13 = 26/78 and 6 × 6/13 × 6 = 36/78

Step 3: Add the Numerators
Now add the numerators (26 + 36 = 62) and keep the common denominator 78 unchanged.
Working: 26 + 36/78 = 62/78

Step 4: Simplify the Fraction to Lowest Terms
Find the Greatest Common Divisor (GCD) of 62 and 78, which is 2. Divide both the numerator and denominator by 2.
Working: 62 ÷ 2/78 ÷ 2 = 31/39

Step 5: Decimal & Percentage Representation
Dividing the numerator 31 by denominator 39 produces a repeating decimal (approximately 0.794872, or 79.4872%).
Working: 31 ÷ 39 = 0.794872 (79.4872%)

Key Values:
- Simplified Fraction: 31/39
- Mixed Number Form: 31/39
- Decimal Value: 0.794872

Step-by-Step Solution: 2/6 + 6/13

Step 1

Find the Least Common Denominator (LCD)

The denominators 6 and 13 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 6 × 13 = 78.

LCD(6, 13) = 78

Step 2

Convert to Equivalent Fractions with Common Denominator 78

Multiply the numerator and denominator of 2/6 by 13, and multiply the numerator and denominator of 6/13 by 6 so both fractions share the common base 78.

2 × 13/6 × 13 = 26/78 and 6 × 6/13 × 6 = 36/78

Step 3

Add the Numerators

Now add the numerators (26 + 36 = 62) and keep the common denominator 78 unchanged.

26 + 36/78 = 62/78

Step 4

Simplify the Fraction to Lowest Terms

Find the Greatest Common Divisor (GCD) of 62 and 78, which is 2. Divide both the numerator and denominator by 2.

62 ÷ 2/78 ÷ 2 = 31/39

Step 5
