What is 7/26 plus 6/13? (Answer: 19/26)

Exact Answer

==================================================
Problem: What is 7/26 plus 6/13?
Formula / Expression: 7/26 + 6/13
Final Answer: 19/26
==================================================

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 7/26 by 1, and multiply the numerator and denominator of 6/13 by 2 so both fractions share the common base 26.
Working: 7 × 1/26 × 1 = 7/26 and 6 × 2/13 × 2 = 12/26

Step 3: Add the Numerators
Now add the numerators (7 + 12 = 19) and keep the common denominator 26 unchanged.
Working: 7 + 12/26 = 19/26

Step 4: Check if the Fraction Can Be Simplified
The Greatest Common Divisor (GCD) of 19 and 26 is 1, confirming that 19/26 cannot be reduced further—it is already in its simplest irreducible form.
Working: 19/26

Step 5: Decimal & Percentage Representation
Dividing the numerator 19 by denominator 26 produces a repeating decimal (approximately 0.730769, or 73.0769%).
Working: 19 ÷ 26 = 0.730769 (73.0769%)

Key Values:
- Simplified Fraction: 19/26
- Mixed Number Form: 19/26
