What is 1/26 plus 2/13? (Answer: 5/26)

Exact Answer

==================================================
Problem: What is 1/26 plus 2/13?
Formula / Expression: 1/26 + 2/13
Final Answer: 5/26
==================================================

Step-by-Step Solution:

Step 1: Find the Least Common Denominator (LCD)
Notice that 26 is an exact multiple of 13 (13 × 2 = 26). The Least Common Denominator (LCD) is simply 26, meaning we only need to scale one fraction.
Working: LCD(26, 13) = 26

Step 2: Convert to Equivalent Fractions with Common Denominator 26
Multiply the numerator and denominator of 1/26 by 1, and multiply the numerator and denominator of 2/13 by 2 so both fractions share the common base 26.
Working: 1 × 1/26 × 1 = 1/26 and 2 × 2/13 × 2 = 4/26

Step 3: Add the Numerators
Now add the numerators (1 + 4 = 5) and keep the common denominator 26 unchanged.
Working: 1 + 4/26 = 5/26

Step 4: Check if the Fraction Can Be Simplified
The Greatest Common Divisor (GCD) of 5 and 26 is 1, confirming that 5/26 cannot be reduced further—it is already in its simplest irreducible form.
Working: 5/26

Step 5: Decimal & Percentage Representation
Dividing the numerator 5 by denominator 26 produces a repeating decimal (approximately 0.192308, or 19.2308%).
Working: 5 ÷ 26 = 0.192308 (19.2308%)

Key Values:
- Simplified Fraction: 5/26
- Mixed Number Form: 5/26
- Decimal Value: 0.192308
- Percentage: 19.2308%
