What is 2/6 plus 9/27? (Answer: 2/3)

Exact Answer

==================================================
Problem: What is 2/6 plus 9/27?
Formula / Expression: 2/6 + 9/27
Final Answer: 2/3
==================================================

Step-by-Step Solution:

Step 1: Find the Least Common Denominator (LCD)
The denominators 6 and 27 share a common factor (GCD = 3). Finding their Least Common Multiple gives an LCD of 54 (which is smaller than their product 6 × 27 = 162, keeping the calculation simpler).
Working: LCD(6, 27) = 54

Step 2: Convert to Equivalent Fractions with Common Denominator 54
Multiply the numerator and denominator of 2/6 by 9, and multiply the numerator and denominator of 9/27 by 2 so both fractions share the common base 54.
Working: 2 × 9/6 × 9 = 18/54 and 9 × 2/27 × 2 = 18/54

Step 3: Add the Numerators
Now add the numerators (18 + 18 = 36) and keep the common denominator 54 unchanged.
Working: 18 + 18/54 = 36/54

Step 4: Simplify the Fraction to Lowest Terms
Find the Greatest Common Divisor (GCD) of 36 and 54, which is 18. Divide both the numerator and denominator by 18.
Working: 36 ÷ 18/54 ÷ 18 = 2/3

Step 5: Decimal & Percentage Representation
Dividing the numerator 2 by denominator 3 produces a repeating decimal (approximately 0.666667, or 66.6667%).
Working: 2 ÷ 3 = 0.666667 (66.6667%)

Key Values:
- Simplified Fraction: 2/3
- Mixed Number Form: 2/3
- Decimal Value: 0.666667
- Percentage: 66.6667%

The denominators 6 and 27 share a common factor (GCD = 3). Finding their Least Common Multiple gives an LCD of 54 (which is smaller than their product 6 × 27 = 162, keeping the calculation simpler).

LCD(6, 27) = 54

Step 2

Convert to Equivalent Fractions with Common Denominator 54

Multiply the numerator and denominator of 2/6 by 9, and multiply the numerator and denominator of 9/27 by 2 so both fractions share the common base 54.

2 × 9/6 × 9 = 18/54 and 9 × 2/27 × 2 = 18/54

Step 3

Add the Numerators

Now add the numerators (18 + 18 = 36) and keep the common denominator 54 unchanged.

18 + 18/54 = 36/54

Step 4

Simplify the Fraction to Lowest Terms

Find the Greatest Common Divisor (GCD) of 36 and 54, which is 18. Divide both the numerator and denominator by 18.

36 ÷ 18/54 ÷ 18 = 2/3

Step 5

Decimal & Percentage Representation

Dividing the numerator 2 by denominator 3 produces a repeating decimal (approximately 0.666667, or 66.6667%).

2 ÷ 3 = 0.666667 (66.6667%)
