What is 8/65 plus 2/13? (Answer: 18/65)

Exact Answer

==================================================
Problem: What is 8/65 plus 2/13?
Formula / Expression: 8/65 + 2/13
Final Answer: 18/65
==================================================

Step-by-Step Solution:

Step 1: Find the Least Common Denominator (LCD)
Notice that 65 is an exact multiple of 13 (13 × 5 = 65). The Least Common Denominator (LCD) is simply 65, meaning we only need to scale one fraction.
Working: LCD(65, 13) = 65

Step 2: Convert to Equivalent Fractions with Common Denominator 65
Multiply the numerator and denominator of 8/65 by 1, and multiply the numerator and denominator of 2/13 by 5 so both fractions share the common base 65.
Working: 8 × 1/65 × 1 = 8/65 and 2 × 5/13 × 5 = 10/65

Step 3: Add the Numerators
Now add the numerators (8 + 10 = 18) and keep the common denominator 65 unchanged.
Working: 8 + 10/65 = 18/65

Step 4: Check if the Fraction Can Be Simplified
The Greatest Common Divisor (GCD) of 18 and 65 is 1, confirming that 18/65 cannot be reduced further—it is already in its simplest irreducible form.
Working: 18/65

Step 5: Decimal & Percentage Representation
Dividing the numerator 18 by denominator 65 produces a repeating decimal (approximately 0.276923, or 27.6923%).
Working: 18 ÷ 65 = 0.276923 (27.6923%)
