Exact Answer

==================================================
Problem: What is 2/19 plus 2/7?
Formula / Expression: 2/19 + 2/7
Final Answer: 52/133
==================================================

Step-by-Step Solution:

Step 1: Find the Least Common Denominator (LCD)
The denominators 19 and 7 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 19 × 7 = 133.
Working: LCD(19, 7) = 133

Step 2: Convert to Equivalent Fractions with Common Denominator 133
Multiply the numerator and denominator of 2/19 by 7, and multiply the numerator and denominator of 2/7 by 19 so both fractions share the common base 133.
Working: 2 × 7/19 × 7 = 14/133 and 2 × 19/7 × 19 = 38/133

Step 3: Add the Numerators
Now add the numerators (14 + 38 = 52) and keep the common denominator 133 unchanged.
Working: 14 + 38/133 = 52/133

Step 4: Check if the Fraction Can Be Simplified
The Greatest Common Divisor (GCD) of 52 and 133 is 1, confirming that 52/133 cannot be reduced further—it is already in its simplest irreducible form.
Working: 52/133

Step 5: Decimal & Percentage Representation
Dividing the numerator 52 by denominator 133 produces a repeating decimal (approximately 0.390977, or 39.0977%).
Working: 52 ÷ 133 = 0.390977 (39.0977%)

Key Values:
- Simplified Fraction: 52/133
- Mixed Number Form: 52/133
- Decimal Value: 0.390977

Step-by-Step Solution: 2/19 + 2/7

Step 1

Find the Least Common Denominator (LCD)

The denominators 19 and 7 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 19 × 7 = 133.

LCD(19, 7) = 133

Step 2

Convert to Equivalent Fractions with Common Denominator 133

Multiply the numerator and denominator of 2/19 by 7, and multiply the numerator and denominator of 2/7 by 19 so both fractions share the common base 133.

2 × 7/19 × 7 = 14/133 and 2 × 19/7 × 19 = 38/133

Step 3

Add the Numerators

Now add the numerators (14 + 38 = 52) and keep the common denominator 133 unchanged.

14 + 38/133 = 52/133

Step 4

Check if the Fraction Can Be Simplified

The Greatest Common Divisor (GCD) of 52 and 133 is 1, confirming that 52/133 cannot be reduced further—it is already in its simplest irreducible form.

52/133

Step 5

Decimal & Percentage Representation
