What is 3/23 plus 4/9? (Answer: 119/207)

Exact Answer

==================================================
Problem: What is 3/23 plus 4/9?
Formula / Expression: 3/23 + 4/9
Final Answer: 119/207
==================================================

Step-by-Step Solution:

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

Step 2: Convert to Equivalent Fractions with Common Denominator 207
Multiply the numerator and denominator of 3/23 by 9, and multiply the numerator and denominator of 4/9 by 23 so both fractions share the common base 207.
Working: 3 × 9/23 × 9 = 27/207 and 4 × 23/9 × 23 = 92/207

Step 3: Add the Numerators
Now add the numerators (27 + 92 = 119) and keep the common denominator 207 unchanged.
Working: 27 + 92/207 = 119/207

Step 4: Check if the Fraction Can Be Simplified
The Greatest Common Divisor (GCD) of 119 and 207 is 1, confirming that 119/207 cannot be reduced further—it is already in its simplest irreducible form.
Working: 119/207

Step 5: Decimal & Percentage Representation
Dividing the numerator 119 by denominator 207 produces a repeating decimal (approximately 0.574879, or 57.4879%).
Working: 119 ÷ 207 = 0.574879 (57.4879%)

Key Values:
- Simplified Fraction: 119/207
- Mixed Number Form: 119/207
- Decimal Value: 0.574879

Step-by-Step Solution: 3/23 + 4/9

Step 1

Find the Least Common Denominator (LCD)

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

LCD(23, 9) = 207

Step 2

Convert to Equivalent Fractions with Common Denominator 207

Multiply the numerator and denominator of 3/23 by 9, and multiply the numerator and denominator of 4/9 by 23 so both fractions share the common base 207.

3 × 9/23 × 9 = 27/207 and 4 × 23/9 × 23 = 92/207

Step 3

Add the Numerators

Now add the numerators (27 + 92 = 119) and keep the common denominator 207 unchanged.

27 + 92/207 = 119/207

Step 4

Check if the Fraction Can Be Simplified

The Greatest Common Divisor (GCD) of 119 and 207 is 1, confirming that 119/207 cannot be reduced further—it is already in its simplest irreducible form.

119/207

Step 5

Decimal & Percentage Representation
