What is 2/23 plus 4/9? (Answer: 110/207)

Exact Answer

==================================================
Problem: What is 2/23 plus 4/9?
Formula / Expression: 2/23 + 4/9
Final Answer: 110/207
==================================================

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 2/23 by 9, and multiply the numerator and denominator of 4/9 by 23 so both fractions share the common base 207.
Working: 2 × 9/23 × 9 = 18/207 and 4 × 23/9 × 23 = 92/207

Step 3: Add the Numerators
Now add the numerators (18 + 92 = 110) and keep the common denominator 207 unchanged.
Working: 18 + 92/207 = 110/207

Step 4: Check if the Fraction Can Be Simplified
The Greatest Common Divisor (GCD) of 110 and 207 is 1, confirming that 110/207 cannot be reduced further—it is already in its simplest irreducible form.
Working: 110/207

Step 5: Decimal & Percentage Representation
Dividing the numerator 110 by denominator 207 produces a repeating decimal (approximately 0.531401, or 53.1401%).
Working: 110 ÷ 207 = 0.531401 (53.1401%)

Key Values:
- Simplified Fraction: 110/207
- Mixed Number Form: 110/207
- Decimal Value: 0.531401
- Percentage: 53.1401%

Step-by-Step Solution: 2/23 + 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 2/23 by 9, and multiply the numerator and denominator of 4/9 by 23 so both fractions share the common base 207.

2 × 9/23 × 9 = 18/207 and 4 × 23/9 × 23 = 92/207

Step 3

Add the Numerators

Now add the numerators (18 + 92 = 110) and keep the common denominator 207 unchanged.

18 + 92/207 = 110/207

Step 4

Check if the Fraction Can Be Simplified

The Greatest Common Divisor (GCD) of 110 and 207 is 1, confirming that 110/207 cannot be reduced further—it is already in its simplest irreducible form.

110/207

Step 5

Decimal & Percentage Representation

Dividing the numerator 110 by denominator 207 produces a repeating decimal (approximately 0.531401, or 53.1401%).

110 ÷ 207 = 0.531401 (53.1401%)
