What is 3/26 plus 10/13? (Answer: 23/26)

Exact Answer

==================================================
Problem: What is 3/26 plus 10/13?
Formula / Expression: 3/26 + 10/13
Final Answer: 23/26
==================================================

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 3/26 by 1, and multiply the numerator and denominator of 10/13 by 2 so both fractions share the common base 26.
Working: 3 × 1/26 × 1 = 3/26 and 10 × 2/13 × 2 = 20/26

Step 3: Add the Numerators
Now add the numerators (3 + 20 = 23) and keep the common denominator 26 unchanged.
Working: 3 + 20/26 = 23/26

Step 4: Check if the Fraction Can Be Simplified
The Greatest Common Divisor (GCD) of 23 and 26 is 1, confirming that 23/26 cannot be reduced further—it is already in its simplest irreducible form.
Working: 23/26

Step 5: Decimal & Percentage Representation
Dividing the numerator 23 by denominator 26 produces a repeating decimal (approximately 0.884615, or 88.4615%).
Working: 23 ÷ 26 = 0.884615 (88.4615%)

Key Values:
- Simplified Fraction: 23/26
- Mixed Number Form: 23/26
