What is 9/41 plus 2/3? (Answer: 109/123)

Exact Answer

==================================================
Problem: What is 9/41 plus 2/3?
Formula / Expression: 9/41 + 2/3
Final Answer: 109/123
==================================================

Step-by-Step Solution:

Step 1: Find the Least Common Denominator (LCD)
The denominators 41 and 3 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 41 × 3 = 123.
Working: LCD(41, 3) = 123

Step 2: Convert to Equivalent Fractions with Common Denominator 123
Multiply the numerator and denominator of 9/41 by 3, and multiply the numerator and denominator of 2/3 by 41 so both fractions share the common base 123.
Working: 9 × 3/41 × 3 = 27/123 and 2 × 41/3 × 41 = 82/123

Step 3: Add the Numerators
Now add the numerators (27 + 82 = 109) and keep the common denominator 123 unchanged.
Working: 27 + 82/123 = 109/123

Step 4: Check if the Fraction Can Be Simplified
The Greatest Common Divisor (GCD) of 109 and 123 is 1, confirming that 109/123 cannot be reduced further—it is already in its simplest irreducible form.
Working: 109/123

Step 5: Decimal & Percentage Representation
Dividing the numerator 109 by denominator 123 produces a repeating decimal (approximately 0.886179, or 88.6179%).
Working: 109 ÷ 123 = 0.886179 (88.6179%)

Key Values:
- Simplified Fraction: 109/123
- Mixed Number Form: 109/123
- Decimal Value: 0.886179

Step-by-Step Solution: 9/41 + 2/3

Step 1

Find the Least Common Denominator (LCD)

The denominators 41 and 3 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 41 × 3 = 123.

LCD(41, 3) = 123

Step 2

Convert to Equivalent Fractions with Common Denominator 123

Multiply the numerator and denominator of 9/41 by 3, and multiply the numerator and denominator of 2/3 by 41 so both fractions share the common base 123.

9 × 3/41 × 3 = 27/123 and 2 × 41/3 × 41 = 82/123

Step 3

Add the Numerators

Now add the numerators (27 + 82 = 109) and keep the common denominator 123 unchanged.

27 + 82/123 = 109/123

Step 4

Check if the Fraction Can Be Simplified

The Greatest Common Divisor (GCD) of 109 and 123 is 1, confirming that 109/123 cannot be reduced further—it is already in its simplest irreducible form.

109/123

Step 5

Decimal & Percentage Representation
