Exact Answer

==================================================
Problem: What is 2/8 plus 8/19?
Formula / Expression: 2/8 + 8/19
Final Answer: 51/76
==================================================

Step-by-Step Solution:

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

Step 2: Convert to Equivalent Fractions with Common Denominator 152
Multiply the numerator and denominator of 2/8 by 19, and multiply the numerator and denominator of 8/19 by 8 so both fractions share the common base 152.
Working: 2 × 19/8 × 19 = 38/152 and 8 × 8/19 × 8 = 64/152

Step 3: Add the Numerators
Now add the numerators (38 + 64 = 102) and keep the common denominator 152 unchanged.
Working: 38 + 64/152 = 102/152

Step 4: Simplify the Fraction to Lowest Terms
Find the Greatest Common Divisor (GCD) of 102 and 152, which is 2. Divide both the numerator and denominator by 2.
Working: 102 ÷ 2/152 ÷ 2 = 51/76

Step 5: Decimal & Percentage Representation
Dividing the numerator 51 by denominator 76 produces a repeating decimal (approximately 0.671053, or 67.1053%).
Working: 51 ÷ 76 = 0.671053 (67.1053%)

Key Values:
- Simplified Fraction: 51/76
- Mixed Number Form: 51/76
- Decimal Value: 0.671053
- Percentage: 67.1053%

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

Step 1

Find the Least Common Denominator (LCD)

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

LCD(8, 19) = 152

Step 2

Convert to Equivalent Fractions with Common Denominator 152

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

2 × 19/8 × 19 = 38/152 and 8 × 8/19 × 8 = 64/152

Step 3

Add the Numerators

Now add the numerators (38 + 64 = 102) and keep the common denominator 152 unchanged.

38 + 64/152 = 102/152

Step 4

Simplify the Fraction to Lowest Terms

Find the Greatest Common Divisor (GCD) of 102 and 152, which is 2. Divide both the numerator and denominator by 2.

102 ÷ 2/152 ÷ 2 = 51/76

Step 5

Decimal & Percentage Representation

Dividing the numerator 51 by denominator 76 produces a repeating decimal (approximately 0.671053, or 67.1053%).

51 ÷ 76 = 0.671053 (67.1053%)
