Exact Answer

==================================================
Problem: What is 2/26 plus 2/3?
Formula / Expression: 2/26 + 2/3
Final Answer: 29/39
==================================================

Step-by-Step Solution:

Step 1: Find the Least Common Denominator (LCD)
The denominators 26 and 3 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 26 × 3 = 78.
Working: LCD(26, 3) = 78

Step 2: Convert to Equivalent Fractions with Common Denominator 78
Multiply the numerator and denominator of 2/26 by 3, and multiply the numerator and denominator of 2/3 by 26 so both fractions share the common base 78.
Working: 2 × 3/26 × 3 = 6/78 and 2 × 26/3 × 26 = 52/78

Step 3: Add the Numerators
Now add the numerators (6 + 52 = 58) and keep the common denominator 78 unchanged.
Working: 6 + 52/78 = 58/78

Step 4: Simplify the Fraction to Lowest Terms
Find the Greatest Common Divisor (GCD) of 58 and 78, which is 2. Divide both the numerator and denominator by 2.
Working: 58 ÷ 2/78 ÷ 2 = 29/39

Step 5: Decimal & Percentage Representation
Dividing the numerator 29 by denominator 39 produces a repeating decimal (approximately 0.74359, or 74.359%).
Working: 29 ÷ 39 = 0.74359 (74.359%)

Key Values:
- Simplified Fraction: 29/39
- Mixed Number Form: 29/39
- Decimal Value: 0.74359
- Percentage: 74.359%

Step-by-Step Solution: 2/26 + 2/3

Step 1

Find the Least Common Denominator (LCD)

The denominators 26 and 3 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 26 × 3 = 78.

LCD(26, 3) = 78

Step 2

Convert to Equivalent Fractions with Common Denominator 78

Multiply the numerator and denominator of 2/26 by 3, and multiply the numerator and denominator of 2/3 by 26 so both fractions share the common base 78.

2 × 3/26 × 3 = 6/78 and 2 × 26/3 × 26 = 52/78

Step 3

Add the Numerators

Now add the numerators (6 + 52 = 58) and keep the common denominator 78 unchanged.

6 + 52/78 = 58/78

Step 4

Simplify the Fraction to Lowest Terms

Find the Greatest Common Divisor (GCD) of 58 and 78, which is 2. Divide both the numerator and denominator by 2.

58 ÷ 2/78 ÷ 2 = 29/39

Step 5
