What is 6/23 plus 2/3? (Answer: 64/69)

Exact Answer

==================================================
Problem: What is 6/23 plus 2/3?
Formula / Expression: 6/23 + 2/3
Final Answer: 64/69
==================================================

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 6/23 by 3, and multiply the numerator and denominator of 2/3 by 23 so both fractions share the common base 69.
Working: 6 × 3/23 × 3 = 18/69 and 2 × 23/3 × 23 = 46/69

Step 3: Add the Numerators
Now add the numerators (18 + 46 = 64) and keep the common denominator 69 unchanged.
Working: 18 + 46/69 = 64/69

Step 4: Check if the Fraction Can Be Simplified
The Greatest Common Divisor (GCD) of 64 and 69 is 1, confirming that 64/69 cannot be reduced further—it is already in its simplest irreducible form.
Working: 64/69

Step 5: Decimal & Percentage Representation
Dividing the numerator 64 by denominator 69 produces a repeating decimal (approximately 0.927536, or 92.7536%).
Working: 64 ÷ 69 = 0.927536 (92.7536%)

Key Values:
- Simplified Fraction: 64/69
- Mixed Number Form: 64/69
- Decimal Value: 0.927536

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 6/23 by 3, and multiply the numerator and denominator of 2/3 by 23 so both fractions share the common base 69.

6 × 3/23 × 3 = 18/69 and 2 × 23/3 × 23 = 46/69

Step 3

Add the Numerators

Now add the numerators (18 + 46 = 64) and keep the common denominator 69 unchanged.

18 + 46/69 = 64/69

Step 4
