Exact Answer

==================================================
Problem: What is 2/9 plus 9/34?
Formula / Expression: 2/9 + 9/34
Final Answer: 149/306
==================================================

Step-by-Step Solution:

Step 1: Find the Least Common Denominator (LCD)
The denominators 9 and 34 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 9 × 34 = 306.
Working: LCD(9, 34) = 306

Step 2: Convert to Equivalent Fractions with Common Denominator 306
Multiply the numerator and denominator of 2/9 by 34, and multiply the numerator and denominator of 9/34 by 9 so both fractions share the common base 306.
Working: 2 × 34/9 × 34 = 68/306 and 9 × 9/34 × 9 = 81/306

Step 3: Add the Numerators
Now add the numerators (68 + 81 = 149) and keep the common denominator 306 unchanged.
Working: 68 + 81/306 = 149/306

Step 4: Check if the Fraction Can Be Simplified
The Greatest Common Divisor (GCD) of 149 and 306 is 1, confirming that 149/306 cannot be reduced further—it is already in its simplest irreducible form.
Working: 149/306

Step 5: Decimal & Percentage Representation
Dividing the numerator 149 by denominator 306 produces a repeating decimal (approximately 0.486928, or 48.6928%).
Working: 149 ÷ 306 = 0.486928 (48.6928%)

Key Values:
- Simplified Fraction: 149/306
- Mixed Number Form: 149/306

Step-by-Step Solution: 2/9 + 9/34

Step 1

Find the Least Common Denominator (LCD)

The denominators 9 and 34 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 9 × 34 = 306.

LCD(9, 34) = 306

Step 2

Convert to Equivalent Fractions with Common Denominator 306

Multiply the numerator and denominator of 2/9 by 34, and multiply the numerator and denominator of 9/34 by 9 so both fractions share the common base 306.

2 × 34/9 × 34 = 68/306 and 9 × 9/34 × 9 = 81/306

Step 3

Add the Numerators

Now add the numerators (68 + 81 = 149) and keep the common denominator 306 unchanged.

68 + 81/306 = 149/306

Step 4

Check if the Fraction Can Be Simplified

The Greatest Common Divisor (GCD) of 149 and 306 is 1, confirming that 149/306 cannot be reduced further—it is already in its simplest irreducible form.
