What is 2/19 plus 4/5? (Answer: 86/95)

Exact Answer

==================================================
Problem: What is 2/19 plus 4/5?
Formula / Expression: 2/19 + 4/5
Final Answer: 86/95
==================================================

Step-by-Step Solution:

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

Step 2: Convert to Equivalent Fractions with Common Denominator 95
Multiply the numerator and denominator of 2/19 by 5, and multiply the numerator and denominator of 4/5 by 19 so both fractions share the common base 95.
Working: 2 × 5/19 × 5 = 10/95 and 4 × 19/5 × 19 = 76/95

Step 3: Add the Numerators
Now add the numerators (10 + 76 = 86) and keep the common denominator 95 unchanged.
Working: 10 + 76/95 = 86/95

Step 4: Check if the Fraction Can Be Simplified
The Greatest Common Divisor (GCD) of 86 and 95 is 1, confirming that 86/95 cannot be reduced further—it is already in its simplest irreducible form.
Working: 86/95

Step 5: Decimal & Percentage Representation
Dividing the numerator 86 by denominator 95 produces a repeating decimal (approximately 0.905263, or 90.5263%).
Working: 86 ÷ 95 = 0.905263 (90.5263%)

Key Values:
- Simplified Fraction: 86/95
- Mixed Number Form: 86/95
- Decimal Value: 0.905263
