Exact Answer

==================================================
Problem: What is 2/19 plus 4/13?
Formula / Expression: 2/19 + 4/13
Final Answer: 102/247
==================================================

Step-by-Step Solution:

Step 1: Find the Least Common Denominator (LCD)
The denominators 19 and 13 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 19 × 13 = 247.
Working: LCD(19, 13) = 247

Step 2: Convert to Equivalent Fractions with Common Denominator 247
Multiply the numerator and denominator of 2/19 by 13, and multiply the numerator and denominator of 4/13 by 19 so both fractions share the common base 247.
Working: 2 × 13/19 × 13 = 26/247 and 4 × 19/13 × 19 = 76/247

Step 3: Add the Numerators
Now add the numerators (26 + 76 = 102) and keep the common denominator 247 unchanged.
Working: 26 + 76/247 = 102/247

Step 4: Check if the Fraction Can Be Simplified
The Greatest Common Divisor (GCD) of 102 and 247 is 1, confirming that 102/247 cannot be reduced further—it is already in its simplest irreducible form.
Working: 102/247

Step 5: Decimal & Percentage Representation
Dividing the numerator 102 by denominator 247 produces a repeating decimal (approximately 0.412955, or 41.2955%).
Working: 102 ÷ 247 = 0.412955 (41.2955%)

Key Values:
- Simplified Fraction: 102/247
- Mixed Number Form: 102/247
- Decimal Value: 0.412955
- Percentage: 41.2955%

Step-by-Step Solution: 2/19 + 4/13

Step 1

Find the Least Common Denominator (LCD)

The denominators 19 and 13 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 19 × 13 = 247.

LCD(19, 13) = 247

Step 2

Convert to Equivalent Fractions with Common Denominator 247

Multiply the numerator and denominator of 2/19 by 13, and multiply the numerator and denominator of 4/13 by 19 so both fractions share the common base 247.

2 × 13/19 × 13 = 26/247 and 4 × 19/13 × 19 = 76/247

Step 3

Add the Numerators

Now add the numerators (26 + 76 = 102) and keep the common denominator 247 unchanged.

26 + 76/247 = 102/247

Step 4

Check if the Fraction Can Be Simplified

The Greatest Common Divisor (GCD) of 102 and 247 is 1, confirming that 102/247 cannot be reduced further—it is already in its simplest irreducible form.
