Exact Answer

==================================================
Problem: What is 9/14 plus 11/13?
Formula / Expression: 9/14 + 11/13
Final Answer: 1 89/182 (271/182)
==================================================

Step-by-Step Solution:

Step 1: Find the Least Common Denominator (LCD)
The denominators 14 and 13 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 14 × 13 = 182.
Working: LCD(14, 13) = 182

Step 2: Convert to Equivalent Fractions with Common Denominator 182
Multiply the numerator and denominator of 9/14 by 13, and multiply the numerator and denominator of 11/13 by 14 so both fractions share the common base 182.
Working: 9 × 13/14 × 13 = 117/182 and 11 × 14/13 × 14 = 154/182

Step 3: Add the Numerators
Now add the numerators (117 + 154 = 271) and keep the common denominator 182 unchanged.
Working: 117 + 154/182 = 271/182

Step 4: Check if the Fraction Can Be Simplified
The Greatest Common Divisor (GCD) of 271 and 182 is 1, confirming that 271/182 cannot be reduced further—it is already in its simplest irreducible form.
Working: 271/182

Step 5: Convert Improper Fraction to a Mixed Number
Since the numerator (271) is greater than the denominator (182), divide 271 by 182: it goes in 1 whole time(s) with a remainder of 89, giving the mixed number 1 89/182.
Working: 271/182 = 1 89/182

Step 6: Decimal & Percentage Representation
Dividing the numerator 271 by denominator 182 produces a repeating decimal (approximately 1.489011, or 148.9011%).
Working: 271 ÷ 182 = 1.489011 (148.9011%)

Key Values:
- Simplified Fraction: 271/182
- Mixed Number Form: 1 89/182
- Decimal Value: 1.489011
- Percentage: 148.9011%

Step-by-Step Solution: 9/14 + 11/13

Step 1

Find the Least Common Denominator (LCD)

The denominators 14 and 13 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 14 × 13 = 182.

LCD(14, 13) = 182

Step 2

Convert to Equivalent Fractions with Common Denominator 182

Multiply the numerator and denominator of 9/14 by 13, and multiply the numerator and denominator of 11/13 by 14 so both fractions share the common base 182.

9 × 13/14 × 13 = 117/182 and 11 × 14/13 × 14 = 154/182

Step 3

Add the Numerators

Now add the numerators (117 + 154 = 271) and keep the common denominator 182 unchanged.

117 + 154/182 = 271/182

Step 4

Check if the Fraction Can Be Simplified

The Greatest Common Divisor (GCD) of 271 and 182 is 1, confirming that 271/182 cannot be reduced further—it is already in its simplest irreducible form.

271/182
