Exact Answer

==================================================
Problem: What is 2/26 plus 8/39?
Formula / Expression: 2/26 + 8/39
Final Answer: 11/39
==================================================

Step-by-Step Solution:

Step 1: Find the Least Common Denominator (LCD)
The denominators 26 and 39 share a common factor (GCD = 13). Finding their Least Common Multiple gives an LCD of 78 (which is smaller than their product 26 × 39 = 1014, keeping the calculation simpler).
Working: LCD(26, 39) = 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 8/39 by 2 so both fractions share the common base 78.
Working: 2 × 3/26 × 3 = 6/78 and 8 × 2/39 × 2 = 16/78

Step 3: Add the Numerators
Now add the numerators (6 + 16 = 22) and keep the common denominator 78 unchanged.
Working: 6 + 16/78 = 22/78

Step 4: Simplify the Fraction to Lowest Terms
Find the Greatest Common Divisor (GCD) of 22 and 78, which is 2. Divide both the numerator and denominator by 2.
Working: 22 ÷ 2/78 ÷ 2 = 11/39

Step 5: Decimal & Percentage Representation
Dividing the numerator 11 by denominator 39 produces a repeating decimal (approximately 0.282051, or 28.2051%).
Working: 11 ÷ 39 = 0.282051 (28.2051%)

Key Values:
- Simplified Fraction: 11/39
- Mixed Number Form: 11/39
- Decimal Value: 0.282051
- Percentage: 28.2051%

Step-by-Step Solution: 2/26 + 8/39

Step 1

Find the Least Common Denominator (LCD)

The denominators 26 and 39 share a common factor (GCD = 13). Finding their Least Common Multiple gives an LCD of 78 (which is smaller than their product 26 × 39 = 1014, keeping the calculation simpler).

LCD(26, 39) = 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 8/39 by 2 so both fractions share the common base 78.

2 × 3/26 × 3 = 6/78 and 8 × 2/39 × 2 = 16/78

Step 3

Add the Numerators

Now add the numerators (6 + 16 = 22) and keep the common denominator 78 unchanged.

6 + 16/78 = 22/78

Step 4

Simplify the Fraction to Lowest Terms

Find the Greatest Common Divisor (GCD) of 22 and 78, which is 2. Divide both the numerator and denominator by 2.

22 ÷ 2/78 ÷ 2 = 11/39

Step 5

Decimal & Percentage Representation

Dividing the numerator 11 by denominator 39 produces a repeating decimal (approximately 0.282051, or 28.2051%).

11 ÷ 39 = 0.282051 (28.2051%)
