Exact Answer

==================================================
Problem: What is 2/9 plus 6/17?
Formula / Expression: 2/9 + 6/17
Final Answer: 88/153
==================================================

Step-by-Step Solution:

Step 1: Find the Least Common Denominator (LCD)
The denominators 9 and 17 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 9 × 17 = 153.
Working: LCD(9, 17) = 153

Step 2: Convert to Equivalent Fractions with Common Denominator 153
Multiply the numerator and denominator of 2/9 by 17, and multiply the numerator and denominator of 6/17 by 9 so both fractions share the common base 153.
Working: 2 × 17/9 × 17 = 34/153 and 6 × 9/17 × 9 = 54/153

Step 3: Add the Numerators
Now add the numerators (34 + 54 = 88) and keep the common denominator 153 unchanged.
Working: 34 + 54/153 = 88/153

Step 4: Check if the Fraction Can Be Simplified
The Greatest Common Divisor (GCD) of 88 and 153 is 1, confirming that 88/153 cannot be reduced further—it is already in its simplest irreducible form.
Working: 88/153

Step 5: Decimal & Percentage Representation
Dividing the numerator 88 by denominator 153 produces a repeating decimal (approximately 0.575163, or 57.5163%).
Working: 88 ÷ 153 = 0.575163 (57.5163%)

Key Values:
- Simplified Fraction: 88/153

The denominators 9 and 17 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 9 × 17 = 153.

LCD(9, 17) = 153

Step 2

Convert to Equivalent Fractions with Common Denominator 153

Multiply the numerator and denominator of 2/9 by 17, and multiply the numerator and denominator of 6/17 by 9 so both fractions share the common base 153.

2 × 17/9 × 17 = 34/153 and 6 × 9/17 × 9 = 54/153

Step 3

Add the Numerators

Now add the numerators (34 + 54 = 88) and keep the common denominator 153 unchanged.

34 + 54/153 = 88/153
