Exact Answer

==================================================
Problem: What is 2/13 plus 2/6?
Formula / Expression: 2/13 + 2/6
Final Answer: 19/39
==================================================

Step-by-Step Solution:

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

Step 2: Convert to Equivalent Fractions with Common Denominator 78
Multiply the numerator and denominator of 2/13 by 6, and multiply the numerator and denominator of 2/6 by 13 so both fractions share the common base 78.
Working: 2 × 6/13 × 6 = 12/78 and 2 × 13/6 × 13 = 26/78

Step 3: Add the Numerators
Now add the numerators (12 + 26 = 38) and keep the common denominator 78 unchanged.
Working: 12 + 26/78 = 38/78

Step 4: Simplify the Fraction to Lowest Terms
Find the Greatest Common Divisor (GCD) of 38 and 78, which is 2. Divide both the numerator and denominator by 2.
Working: 38 ÷ 2/78 ÷ 2 = 19/39

Step 5: Decimal & Percentage Representation
Dividing the numerator 19 by denominator 39 produces a repeating decimal (approximately 0.487179, or 48.7179%).
Working: 19 ÷ 39 = 0.487179 (48.7179%)

Key Values:
- Simplified Fraction: 19/39
- Mixed Number Form: 19/39
- Decimal Value: 0.487179

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

Step 1

Find the Least Common Denominator (LCD)

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

LCD(13, 6) = 78

Step 2

Convert to Equivalent Fractions with Common Denominator 78

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

2 × 6/13 × 6 = 12/78 and 2 × 13/6 × 13 = 26/78

Step 3

Add the Numerators

Now add the numerators (12 + 26 = 38) and keep the common denominator 78 unchanged.

12 + 26/78 = 38/78

Step 4

Simplify the Fraction to Lowest Terms

Find the Greatest Common Divisor (GCD) of 38 and 78, which is 2. Divide both the numerator and denominator by 2.

38 ÷ 2/78 ÷ 2 = 19/39

Step 5

Decimal & Percentage Representation

Dividing the numerator 19 by denominator 39 produces a repeating decimal (approximately 0.487179, or 48.7179%).

19 ÷ 39 = 0.487179 (48.7179%)
