What is 2/19 plus 2/3? (Answer: 44/57)

Exact Answer

==================================================
Problem: What is 2/19 plus 2/3?
Formula / Expression: 2/19 + 2/3
Final Answer: 44/57
==================================================

Step-by-Step Solution:

Step 1: Find the Least Common Denominator (LCD)
The denominators 19 and 3 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 19 × 3 = 57.
Working: LCD(19, 3) = 57

Step 2: Convert to Equivalent Fractions with Common Denominator 57
Multiply the numerator and denominator of 2/19 by 3, and multiply the numerator and denominator of 2/3 by 19 so both fractions share the common base 57.
Working: 2 × 3/19 × 3 = 6/57 and 2 × 19/3 × 19 = 38/57

Step 3: Add the Numerators
Now add the numerators (6 + 38 = 44) and keep the common denominator 57 unchanged.
Working: 6 + 38/57 = 44/57

Step 4: Check if the Fraction Can Be Simplified
The Greatest Common Divisor (GCD) of 44 and 57 is 1, confirming that 44/57 cannot be reduced further—it is already in its simplest irreducible form.
Working: 44/57

Step 5: Decimal & Percentage Representation
Dividing the numerator 44 by denominator 57 produces a repeating decimal (approximately 0.77193, or 77.193%).
Working: 44 ÷ 57 = 0.77193 (77.193%)

Key Values:
- Simplified Fraction: 44/57
- Mixed Number Form: 44/57
- Decimal Value: 0.77193
- Percentage: 77.193%

Step-by-Step Solution: 2/19 + 2/3

Step 1

Find the Least Common Denominator (LCD)

The denominators 19 and 3 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 19 × 3 = 57.

LCD(19, 3) = 57

Step 2

Convert to Equivalent Fractions with Common Denominator 57

Multiply the numerator and denominator of 2/19 by 3, and multiply the numerator and denominator of 2/3 by 19 so both fractions share the common base 57.

2 × 3/19 × 3 = 6/57 and 2 × 19/3 × 19 = 38/57

Step 3

Add the Numerators

Now add the numerators (6 + 38 = 44) and keep the common denominator 57 unchanged.

6 + 38/57 = 44/57

Step 4

Check if the Fraction Can Be Simplified

The Greatest Common Divisor (GCD) of 44 and 57 is 1, confirming that 44/57 cannot be reduced further—it is already in its simplest irreducible form.

44/57

Step 5

Decimal & Percentage Representation

Dividing the numerator 44 by denominator 57 produces a repeating decimal (approximately 0.77193, or 77.193%).
