Exact Answer

==================================================
Problem: What is 2/9 plus 6/19?
Formula / Expression: 2/9 + 6/19
Final Answer: 92/171
==================================================

Step-by-Step Solution:

Step 1: Find the Least Common Denominator (LCD)
The denominators 9 and 19 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 9 × 19 = 171.
Working: LCD(9, 19) = 171

Step 2: Convert to Equivalent Fractions with Common Denominator 171
Multiply the numerator and denominator of 2/9 by 19, and multiply the numerator and denominator of 6/19 by 9 so both fractions share the common base 171.
Working: 2 × 19/9 × 19 = 38/171 and 6 × 9/19 × 9 = 54/171

Step 3: Add the Numerators
Now add the numerators (38 + 54 = 92) and keep the common denominator 171 unchanged.
Working: 38 + 54/171 = 92/171

Step 4: Check if the Fraction Can Be Simplified
The Greatest Common Divisor (GCD) of 92 and 171 is 1, confirming that 92/171 cannot be reduced further—it is already in its simplest irreducible form.
Working: 92/171

Step 5: Decimal & Percentage Representation
Dividing the numerator 92 by denominator 171 produces a repeating decimal (approximately 0.538012, or 53.8012%).
Working: 92 ÷ 171 = 0.538012 (53.8012%)

Key Values:
- Simplified Fraction: 92/171
- Mixed Number Form: 92/171
- Decimal Value: 0.538012

The denominators 9 and 19 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 9 × 19 = 171.

LCD(9, 19) = 171

Step 2

Convert to Equivalent Fractions with Common Denominator 171

Multiply the numerator and denominator of 2/9 by 19, and multiply the numerator and denominator of 6/19 by 9 so both fractions share the common base 171.

2 × 19/9 × 19 = 38/171 and 6 × 9/19 × 9 = 54/171

Step 3

Add the Numerators

Now add the numerators (38 + 54 = 92) and keep the common denominator 171 unchanged.

38 + 54/171 = 92/171
