What is 3/19 plus 2/4? (Answer: 25/38)

Exact Answer

==================================================
Problem: What is 3/19 plus 2/4?
Formula / Expression: 3/19 + 2/4
Final Answer: 25/38
==================================================

Step-by-Step Solution:

Step 1: Find the Least Common Denominator (LCD)
The denominators 19 and 4 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 19 × 4 = 76.
Working: LCD(19, 4) = 76

Step 2: Convert to Equivalent Fractions with Common Denominator 76
Multiply the numerator and denominator of 3/19 by 4, and multiply the numerator and denominator of 2/4 by 19 so both fractions share the common base 76.
Working: 3 × 4/19 × 4 = 12/76 and 2 × 19/4 × 19 = 38/76

Step 3: Add the Numerators
Now add the numerators (12 + 38 = 50) and keep the common denominator 76 unchanged.
Working: 12 + 38/76 = 50/76

Step 4: Simplify the Fraction to Lowest Terms
Find the Greatest Common Divisor (GCD) of 50 and 76, which is 2. Divide both the numerator and denominator by 2.
Working: 50 ÷ 2/76 ÷ 2 = 25/38

Step 5: Decimal & Percentage Representation
Dividing the numerator 25 by denominator 38 produces a repeating decimal (approximately 0.657895, or 65.7895%).
Working: 25 ÷ 38 = 0.657895 (65.7895%)

Key Values:
- Simplified Fraction: 25/38
- Mixed Number Form: 25/38
- Decimal Value: 0.657895
- Percentage: 65.7895%

Step-by-Step Solution: 3/19 + 2/4

Step 1

Find the Least Common Denominator (LCD)

The denominators 19 and 4 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 19 × 4 = 76.

LCD(19, 4) = 76

Step 2

Convert to Equivalent Fractions with Common Denominator 76

Multiply the numerator and denominator of 3/19 by 4, and multiply the numerator and denominator of 2/4 by 19 so both fractions share the common base 76.

3 × 4/19 × 4 = 12/76 and 2 × 19/4 × 19 = 38/76

Step 3

Add the Numerators

Now add the numerators (12 + 38 = 50) and keep the common denominator 76 unchanged.

12 + 38/76 = 50/76

Step 4

Simplify the Fraction to Lowest Terms

Find the Greatest Common Divisor (GCD) of 50 and 76, which is 2. Divide both the numerator and denominator by 2.

50 ÷ 2/76 ÷ 2 = 25/38

Step 5

Decimal & Percentage Representation

Dividing the numerator 25 by denominator 38 produces a repeating decimal (approximately 0.657895, or 65.7895%).

25 ÷ 38 = 0.657895 (65.7895%)
