What is 6/13 plus 11/13? (Answer: 17/13)

Exact Answer

==================================================
Problem: What is 6/13 plus 11/13?
Formula / Expression: 6/13 + 11/13
Final Answer: 1 4/13 (17/13)
==================================================

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: 6/13 + 11/13

Step 2: Add the Numerators
Now add the numerators (6 + 11 = 17) and keep the common denominator 13 unchanged.
Working: 6 + 11/13 = 17/13

Step 3: Check if the Fraction Can Be Simplified
The Greatest Common Divisor (GCD) of 17 and 13 is 1, confirming that 17/13 cannot be reduced further—it is already in its simplest irreducible form.
Working: 17/13

Step 4: Convert Improper Fraction to a Mixed Number
Since the numerator (17) is greater than the denominator (13), divide 17 by 13: it goes in 1 whole time(s) with a remainder of 4, giving the mixed number 1 4/13.
Working: 17/13 = 1 4/13

Step 5: Decimal & Percentage Representation
Dividing the numerator 17 by denominator 13 produces a repeating decimal (approximately 1.307692, or 130.7692%).
Working: 17 ÷ 13 = 1.307692 (130.7692%)

Key Values:
- Simplified Fraction: 17/13
- Mixed Number Form: 1 4/13
- Decimal Value: 1.307692
- Percentage: 130.7692%
