Exact Answer

==================================================
Problem: What is 9/26 plus 4/9?
Formula / Expression: 9/26 + 4/9
Final Answer: 185/234
==================================================

Step-by-Step Solution:

Step 1: Find the Least Common Denominator (LCD)
The denominators 26 and 9 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 26 × 9 = 234.
Working: LCD(26, 9) = 234

Step 2: Convert to Equivalent Fractions with Common Denominator 234
Multiply the numerator and denominator of 9/26 by 9, and multiply the numerator and denominator of 4/9 by 26 so both fractions share the common base 234.
Working: 9 × 9/26 × 9 = 81/234 and 4 × 26/9 × 26 = 104/234

Step 3: Add the Numerators
Now add the numerators (81 + 104 = 185) and keep the common denominator 234 unchanged.
Working: 81 + 104/234 = 185/234

Step 4: Check if the Fraction Can Be Simplified
The Greatest Common Divisor (GCD) of 185 and 234 is 1, confirming that 185/234 cannot be reduced further—it is already in its simplest irreducible form.
Working: 185/234

Step 5: Decimal & Percentage Representation
Dividing the numerator 185 by denominator 234 produces a repeating decimal (approximately 0.790598, or 79.0598%).
Working: 185 ÷ 234 = 0.790598 (79.0598%)

Key Values:
- Simplified Fraction: 185/234
- Mixed Number Form: 185/234
- Decimal Value: 0.790598
- Percentage: 79.0598%

Step-by-Step Solution: 9/26 + 4/9

Step 1

Find the Least Common Denominator (LCD)

The denominators 26 and 9 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 26 × 9 = 234.

LCD(26, 9) = 234

Step 2

Convert to Equivalent Fractions with Common Denominator 234

Multiply the numerator and denominator of 9/26 by 9, and multiply the numerator and denominator of 4/9 by 26 so both fractions share the common base 234.

9 × 9/26 × 9 = 81/234 and 4 × 26/9 × 26 = 104/234

Step 3

Add the Numerators

Now add the numerators (81 + 104 = 185) and keep the common denominator 234 unchanged.

81 + 104/234 = 185/234

Step 4

Check if the Fraction Can Be Simplified

The Greatest Common Divisor (GCD) of 185 and 234 is 1, confirming that 185/234 cannot be reduced further—it is already in its simplest irreducible form.
