Exact Answer

==================================================
Problem: What is 2/19 plus 4/8?
Formula / Expression: 2/19 + 4/8
Final Answer: 23/38
==================================================

Step-by-Step Solution:

Step 1: Find the Least Common Denominator (LCD)
The denominators 19 and 8 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 19 × 8 = 152.
Working: LCD(19, 8) = 152

Step 2: Convert to Equivalent Fractions with Common Denominator 152
Multiply the numerator and denominator of 2/19 by 8, and multiply the numerator and denominator of 4/8 by 19 so both fractions share the common base 152.
Working: 2 × 8/19 × 8 = 16/152 and 4 × 19/8 × 19 = 76/152

Step 3: Add the Numerators
Now add the numerators (16 + 76 = 92) and keep the common denominator 152 unchanged.
Working: 16 + 76/152 = 92/152

Step 4: Simplify the Fraction to Lowest Terms
Find the Greatest Common Divisor (GCD) of 92 and 152, which is 4. Divide both the numerator and denominator by 4.
Working: 92 ÷ 4/152 ÷ 4 = 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%

Step-by-Step Solution: 2/19 + 4/8

Step 1

Find the Least Common Denominator (LCD)

The denominators 19 and 8 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 19 × 8 = 152.

LCD(19, 8) = 152

Step 2

Convert to Equivalent Fractions with Common Denominator 152

Multiply the numerator and denominator of 2/19 by 8, and multiply the numerator and denominator of 4/8 by 19 so both fractions share the common base 152.

2 × 8/19 × 8 = 16/152 and 4 × 19/8 × 19 = 76/152

Step 3

Add the Numerators

Now add the numerators (16 + 76 = 92) and keep the common denominator 152 unchanged.

16 + 76/152 = 92/152

Step 4

Simplify the Fraction to Lowest Terms

Find the Greatest Common Divisor (GCD) of 92 and 152, which is 4. Divide both the numerator and denominator by 4.

92 ÷ 4/152 ÷ 4 = 23/38

Step 5

Decimal & Percentage Representation

Dividing the numerator 23 by denominator 38 produces a repeating decimal (approximately 0.605263, or 60.5263%).

23 ÷ 38 = 0.605263 (60.5263%)
