Exact Answer

==================================================
Problem: What is 8/27 plus 2/4?
Formula / Expression: 8/27 + 2/4
Final Answer: 43/54
==================================================

Step-by-Step Solution:

Step 1: Find the Least Common Denominator (LCD)
The denominators 27 and 4 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 27 × 4 = 108.
Working: LCD(27, 4) = 108

Step 2: Convert to Equivalent Fractions with Common Denominator 108
Multiply the numerator and denominator of 8/27 by 4, and multiply the numerator and denominator of 2/4 by 27 so both fractions share the common base 108.
Working: 8 × 4/27 × 4 = 32/108 and 2 × 27/4 × 27 = 54/108

Step 3: Add the Numerators
Now add the numerators (32 + 54 = 86) and keep the common denominator 108 unchanged.
Working: 32 + 54/108 = 86/108

Step 4: Simplify the Fraction to Lowest Terms
Find the Greatest Common Divisor (GCD) of 86 and 108, which is 2. Divide both the numerator and denominator by 2.
Working: 86 ÷ 2/108 ÷ 2 = 43/54

Step 5: Decimal & Percentage Representation
Dividing the numerator 43 by denominator 54 produces a repeating decimal (approximately 0.796296, or 79.6296%).
Working: 43 ÷ 54 = 0.796296 (79.6296%)

Key Values:
- Simplified Fraction: 43/54
- Mixed Number Form: 43/54
- Decimal Value: 0.796296
- Percentage: 79.6296%

Step-by-Step Solution: 8/27 + 2/4

Step 1

Find the Least Common Denominator (LCD)

The denominators 27 and 4 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 27 × 4 = 108.

LCD(27, 4) = 108

Step 2

Convert to Equivalent Fractions with Common Denominator 108

Multiply the numerator and denominator of 8/27 by 4, and multiply the numerator and denominator of 2/4 by 27 so both fractions share the common base 108.

8 × 4/27 × 4 = 32/108 and 2 × 27/4 × 27 = 54/108

Step 3

Add the Numerators

Now add the numerators (32 + 54 = 86) and keep the common denominator 108 unchanged.

32 + 54/108 = 86/108

Step 4

Simplify the Fraction to Lowest Terms

Find the Greatest Common Divisor (GCD) of 86 and 108, which is 2. Divide both the numerator and denominator by 2.

86 ÷ 2/108 ÷ 2 = 43/54

Step 5

Decimal & Percentage Representation

Dividing the numerator 43 by denominator 54 produces a repeating decimal (approximately 0.796296, or 79.6296%).

43 ÷ 54 = 0.796296 (79.6296%)
