Exact Answer

==================================================
Problem: What is 2/11 plus 9/17?
Formula / Expression: 2/11 + 9/17
Final Answer: 133/187
==================================================

Step-by-Step Solution:

Step 1: Find the Least Common Denominator (LCD)
The denominators 11 and 17 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 11 × 17 = 187.
Working: LCD(11, 17) = 187

Step 2: Convert to Equivalent Fractions with Common Denominator 187
Multiply the numerator and denominator of 2/11 by 17, and multiply the numerator and denominator of 9/17 by 11 so both fractions share the common base 187.
Working: 2 × 17/11 × 17 = 34/187 and 9 × 11/17 × 11 = 99/187

Step 3: Add the Numerators
Now add the numerators (34 + 99 = 133) and keep the common denominator 187 unchanged.
Working: 34 + 99/187 = 133/187

Step 4: Check if the Fraction Can Be Simplified
The Greatest Common Divisor (GCD) of 133 and 187 is 1, confirming that 133/187 cannot be reduced further—it is already in its simplest irreducible form.
Working: 133/187

Step 5: Decimal & Percentage Representation
Dividing the numerator 133 by denominator 187 produces a repeating decimal (approximately 0.71123, or 71.123%).
Working: 133 ÷ 187 = 0.71123 (71.123%)

Key Values:
- Simplified Fraction: 133/187
- Mixed Number Form: 133/187
- Decimal Value: 0.71123
- Percentage: 71.123%

Step-by-Step Solution: 2/11 + 9/17

Step 1

Find the Least Common Denominator (LCD)

The denominators 11 and 17 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 11 × 17 = 187.

LCD(11, 17) = 187

Step 2

Convert to Equivalent Fractions with Common Denominator 187

Multiply the numerator and denominator of 2/11 by 17, and multiply the numerator and denominator of 9/17 by 11 so both fractions share the common base 187.

2 × 17/11 × 17 = 34/187 and 9 × 11/17 × 11 = 99/187

Step 3

Add the Numerators

Now add the numerators (34 + 99 = 133) and keep the common denominator 187 unchanged.

34 + 99/187 = 133/187

Step 4

Check if the Fraction Can Be Simplified

The Greatest Common Divisor (GCD) of 133 and 187 is 1, confirming that 133/187 cannot be reduced further—it is already in its simplest irreducible form.
