What is 7/26 plus 2/3? (Answer: 73/78)

Exact Answer

==================================================
Problem: What is 7/26 plus 2/3?
Formula / Expression: 7/26 + 2/3
Final Answer: 73/78
==================================================

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 7/26 by 3, and multiply the numerator and denominator of 2/3 by 26 so both fractions share the common base 78.
Working: 7 × 3/26 × 3 = 21/78 and 2 × 26/3 × 26 = 52/78

Step 3: Add the Numerators
Now add the numerators (21 + 52 = 73) and keep the common denominator 78 unchanged.
Working: 21 + 52/78 = 73/78

Step 4: Check if the Fraction Can Be Simplified
The Greatest Common Divisor (GCD) of 73 and 78 is 1, confirming that 73/78 cannot be reduced further—it is already in its simplest irreducible form.
Working: 73/78

Step 5: Decimal & Percentage Representation
Dividing the numerator 73 by denominator 78 produces a repeating decimal (approximately 0.935897, or 93.5897%).
Working: 73 ÷ 78 = 0.935897 (93.5897%)

Key Values:
- Simplified Fraction: 73/78
- Mixed Number Form: 73/78
