What is 5/13 plus 9/13? (Answer: 14/13)

Exact Answer

==================================================
Problem: What is 5/13 plus 9/13?
Formula / Expression: 5/13 + 9/13
Final Answer: 1 1/13 (14/13)
==================================================

Step-by-Step Solution:

Step 1: Check the Denominators (Like Fractions)
Both fractions already share the identical denominator (13). Because these are like fractions, no conversion to a common denominator is required—we directly add their numerators while keeping the denominator 13.
Working: 5/13 + 9/13

Step 2: Add the Numerators
Now add the numerators (5 + 9 = 14) and keep the common denominator 13 unchanged.
Working: 5 + 9/13 = 14/13

Step 3: Check if the Fraction Can Be Simplified
The Greatest Common Divisor (GCD) of 14 and 13 is 1, confirming that 14/13 cannot be reduced further—it is already in its simplest irreducible form.
Working: 14/13

Step 4: Convert Improper Fraction to a Mixed Number
Since the numerator (14) is greater than the denominator (13), divide 14 by 13: it goes in 1 whole time(s) with a remainder of 1, giving the mixed number 1 1/13.
Working: 14/13 = 1 1/13

Step 5: Decimal & Percentage Representation
Dividing the numerator 14 by denominator 13 produces a repeating decimal (approximately 1.076923, or 107.6923%).
Working: 14 ÷ 13 = 1.076923 (107.6923%)

Key Values:
- Simplified Fraction: 14/13
- Mixed Number Form: 1 1/13
- Decimal Value: 1.076923
- Percentage: 107.6923%
