What is 2/19 plus 1/2? (Answer: 23/38)

Exact Answer

==================================================
Problem: What is 2/19 plus 1/2?
Formula / Expression: 2/19 + 1/2
Final Answer: 23/38
==================================================

Step-by-Step Solution:

Step 1: Find the Least Common Denominator (LCD)
The denominators 19 and 2 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 19 × 2 = 38.
Working: LCD(19, 2) = 38

Step 2: Convert to Equivalent Fractions with Common Denominator 38
Multiply the numerator and denominator of 2/19 by 2, and multiply the numerator and denominator of 1/2 by 19 so both fractions share the common base 38.
Working: 2 × 2/19 × 2 = 4/38 and 1 × 19/2 × 19 = 19/38

Step 3: Add the Numerators
Now add the numerators (4 + 19 = 23) and keep the common denominator 38 unchanged.
Working: 4 + 19/38 = 23/38

Step 4: Check if the Fraction Can Be Simplified
The Greatest Common Divisor (GCD) of 23 and 38 is 1, confirming that 23/38 cannot be reduced further—it is already in its simplest irreducible form.
Working: 23/38

Step 5: Decimal & Percentage Representation
Dividing the numerator 23 by denominator 38 produces a repeating decimal (approximately 0.605263, or 60.5263%).
Working: 23 ÷ 38 = 0.605263 (60.5263%)

Key Values:
- Simplified Fraction: 23/38
- Mixed Number Form: 23/38
- Decimal Value: 0.605263
- Percentage: 60.5263%

Find the Least Common Denominator (LCD)

The denominators 19 and 2 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 19 × 2 = 38.

LCD(19, 2) = 38

Step 2

Convert to Equivalent Fractions with Common Denominator 38

Multiply the numerator and denominator of 2/19 by 2, and multiply the numerator and denominator of 1/2 by 19 so both fractions share the common base 38.

2 × 2/19 × 2 = 4/38 and 1 × 19/2 × 19 = 19/38

Step 3

Add the Numerators

Now add the numerators (4 + 19 = 23) and keep the common denominator 38 unchanged.

4 + 19/38 = 23/38

Step 4

Check if the Fraction Can Be Simplified

The Greatest Common Divisor (GCD) of 23 and 38 is 1, confirming that 23/38 cannot be reduced further—it is already in its simplest irreducible form.
