What is 8/27 plus 2/3? (Answer: 26/27)

Exact Answer

==================================================
Problem: What is 8/27 plus 2/3?
Formula / Expression: 8/27 + 2/3
Final Answer: 26/27
==================================================

Step-by-Step Solution:

Step 1: Find the Least Common Denominator (LCD)
Notice that 27 is an exact multiple of 3 (3 × 9 = 27). The Least Common Denominator (LCD) is simply 27, meaning we only need to scale one fraction.
Working: LCD(27, 3) = 27

Step 2: Convert to Equivalent Fractions with Common Denominator 27
Multiply the numerator and denominator of 8/27 by 1, and multiply the numerator and denominator of 2/3 by 9 so both fractions share the common base 27.
Working: 8 × 1/27 × 1 = 8/27 and 2 × 9/3 × 9 = 18/27

Step 3: Add the Numerators
Now add the numerators (8 + 18 = 26) and keep the common denominator 27 unchanged.
Working: 8 + 18/27 = 26/27

Step 4: Check if the Fraction Can Be Simplified
The Greatest Common Divisor (GCD) of 26 and 27 is 1, confirming that 26/27 cannot be reduced further—it is already in its simplest irreducible form.
Working: 26/27

Step 5: Decimal & Percentage Representation
Dividing the numerator 26 by denominator 27 produces a repeating decimal (approximately 0.962963, or 96.2963%).
Working: 26 ÷ 27 = 0.962963 (96.2963%)

Key Values:
- Simplified Fraction: 26/27
- Mixed Number Form: 26/27
- Decimal Value: 0.962963
