What is 2/5 plus 10/19? (Answer: 88/95)

Exact Answer

==================================================
Problem: What is 2/5 plus 10/19?
Formula / Expression: 2/5 + 10/19
Final Answer: 88/95
==================================================

Step-by-Step Solution:

Step 1: Find the Least Common Denominator (LCD)
The denominators 5 and 19 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 5 × 19 = 95.
Working: LCD(5, 19) = 95

Step 2: Convert to Equivalent Fractions with Common Denominator 95
Multiply the numerator and denominator of 2/5 by 19, and multiply the numerator and denominator of 10/19 by 5 so both fractions share the common base 95.
Working: 2 × 19/5 × 19 = 38/95 and 10 × 5/19 × 5 = 50/95

Step 3: Add the Numerators
Now add the numerators (38 + 50 = 88) and keep the common denominator 95 unchanged.
Working: 38 + 50/95 = 88/95

Step 4: Check if the Fraction Can Be Simplified
The Greatest Common Divisor (GCD) of 88 and 95 is 1, confirming that 88/95 cannot be reduced further—it is already in its simplest irreducible form.
Working: 88/95

Step 5: Decimal & Percentage Representation
Dividing the numerator 88 by denominator 95 produces a repeating decimal (approximately 0.926316, or 92.6316%).
Working: 88 ÷ 95 = 0.926316 (92.6316%)

Key Values:
- Simplified Fraction: 88/95
- Mixed Number Form: 88/95
