What is 2/23 plus 2/3? (Answer: 52/69)

Exact Answer

==================================================
Problem: What is 2/23 plus 2/3?
Formula / Expression: 2/23 + 2/3
Final Answer: 52/69
==================================================

Step-by-Step Solution:

Step 1: Find the Least Common Denominator (LCD)
The denominators 23 and 3 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 23 × 3 = 69.
Working: LCD(23, 3) = 69

Step 2: Convert to Equivalent Fractions with Common Denominator 69
Multiply the numerator and denominator of 2/23 by 3, and multiply the numerator and denominator of 2/3 by 23 so both fractions share the common base 69.
Working: 2 × 3/23 × 3 = 6/69 and 2 × 23/3 × 23 = 46/69

Step 3: Add the Numerators
Now add the numerators (6 + 46 = 52) and keep the common denominator 69 unchanged.
Working: 6 + 46/69 = 52/69

Step 4: Check if the Fraction Can Be Simplified
The Greatest Common Divisor (GCD) of 52 and 69 is 1, confirming that 52/69 cannot be reduced further—it is already in its simplest irreducible form.
Working: 52/69

Step 5: Decimal & Percentage Representation
Dividing the numerator 52 by denominator 69 produces a repeating decimal (approximately 0.753623, or 75.3623%).
Working: 52 ÷ 69 = 0.753623 (75.3623%)

Key Values:
- Simplified Fraction: 52/69
- Mixed Number Form: 52/69
- Decimal Value: 0.753623
- Percentage: 75.3623%

Step-by-Step Solution: 2/23 + 2/3

Step 1

Find the Least Common Denominator (LCD)

The denominators 23 and 3 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 23 × 3 = 69.

LCD(23, 3) = 69

Step 2

Convert to Equivalent Fractions with Common Denominator 69

Multiply the numerator and denominator of 2/23 by 3, and multiply the numerator and denominator of 2/3 by 23 so both fractions share the common base 69.

2 × 3/23 × 3 = 6/69 and 2 × 23/3 × 23 = 46/69

Step 3

Add the Numerators

Now add the numerators (6 + 46 = 52) and keep the common denominator 69 unchanged.

6 + 46/69 = 52/69

Step 4

Check if the Fraction Can Be Simplified

The Greatest Common Divisor (GCD) of 52 and 69 is 1, confirming that 52/69 cannot be reduced further—it is already in its simplest irreducible form.
