Exact Answer

==================================================
Problem: What is 2/9 plus 9/23?
Formula / Expression: 2/9 + 9/23
Final Answer: 127/207
==================================================

Step-by-Step Solution:

Step 1: Find the Least Common Denominator (LCD)
The denominators 9 and 23 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 9 × 23 = 207.
Working: LCD(9, 23) = 207

Step 2: Convert to Equivalent Fractions with Common Denominator 207
Multiply the numerator and denominator of 2/9 by 23, and multiply the numerator and denominator of 9/23 by 9 so both fractions share the common base 207.
Working: 2 × 23/9 × 23 = 46/207 and 9 × 9/23 × 9 = 81/207

Step 3: Add the Numerators
Now add the numerators (46 + 81 = 127) and keep the common denominator 207 unchanged.
Working: 46 + 81/207 = 127/207

Step 4: Check if the Fraction Can Be Simplified
The Greatest Common Divisor (GCD) of 127 and 207 is 1, confirming that 127/207 cannot be reduced further—it is already in its simplest irreducible form.
Working: 127/207

Step 5: Decimal & Percentage Representation
Dividing the numerator 127 by denominator 207 produces a repeating decimal (approximately 0.613527, or 61.3527%).
Working: 127 ÷ 207 = 0.613527 (61.3527%)

Key Values:
- Simplified Fraction: 127/207
- Mixed Number Form: 127/207
- Decimal Value: 0.613527

Step-by-Step Solution: 2/9 + 9/23

Step 1

Find the Least Common Denominator (LCD)

The denominators 9 and 23 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 9 × 23 = 207.

LCD(9, 23) = 207

Step 2

Convert to Equivalent Fractions with Common Denominator 207

Multiply the numerator and denominator of 2/9 by 23, and multiply the numerator and denominator of 9/23 by 9 so both fractions share the common base 207.

2 × 23/9 × 23 = 46/207 and 9 × 9/23 × 9 = 81/207

Step 3

Add the Numerators

Now add the numerators (46 + 81 = 127) and keep the common denominator 207 unchanged.

46 + 81/207 = 127/207

Step 4

Check if the Fraction Can Be Simplified

The Greatest Common Divisor (GCD) of 127 and 207 is 1, confirming that 127/207 cannot be reduced further—it is already in its simplest irreducible form.
