What is 2/41 plus 3/5? (Answer: 133/205)

Exact Answer

==================================================
Problem: What is 2/41 plus 3/5?
Formula / Expression: 2/41 + 3/5
Final Answer: 133/205
==================================================

Step-by-Step Solution:

Step 1: Find the Least Common Denominator (LCD)
The denominators 41 and 5 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 41 × 5 = 205.
Working: LCD(41, 5) = 205

Step 2: Convert to Equivalent Fractions with Common Denominator 205
Multiply the numerator and denominator of 2/41 by 5, and multiply the numerator and denominator of 3/5 by 41 so both fractions share the common base 205.
Working: 2 × 5/41 × 5 = 10/205 and 3 × 41/5 × 41 = 123/205

Step 3: Add the Numerators
Now add the numerators (10 + 123 = 133) and keep the common denominator 205 unchanged.
Working: 10 + 123/205 = 133/205

Step 4: Check if the Fraction Can Be Simplified
The Greatest Common Divisor (GCD) of 133 and 205 is 1, confirming that 133/205 cannot be reduced further—it is already in its simplest irreducible form.
Working: 133/205

Step 5: Decimal & Percentage Representation
Dividing the numerator 133 by denominator 205 produces a repeating decimal (approximately 0.64878, or 64.878%).
Working: 133 ÷ 205 = 0.64878 (64.878%)

Key Values:
- Simplified Fraction: 133/205
- Mixed Number Form: 133/205
- Decimal Value: 0.64878
- Percentage: 64.878%

Step-by-Step Solution: 2/41 + 3/5

Step 1

Find the Least Common Denominator (LCD)

The denominators 41 and 5 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 41 × 5 = 205.

LCD(41, 5) = 205

Step 2

Convert to Equivalent Fractions with Common Denominator 205

Multiply the numerator and denominator of 2/41 by 5, and multiply the numerator and denominator of 3/5 by 41 so both fractions share the common base 205.

2 × 5/41 × 5 = 10/205 and 3 × 41/5 × 41 = 123/205

Step 3

Add the Numerators

Now add the numerators (10 + 123 = 133) and keep the common denominator 205 unchanged.

10 + 123/205 = 133/205

Step 4

Check if the Fraction Can Be Simplified

The Greatest Common Divisor (GCD) of 133 and 205 is 1, confirming that 133/205 cannot be reduced further—it is already in its simplest irreducible form.

133/205

Step 5

Decimal & Percentage Representation

Dividing the numerator 133 by denominator 205 produces a repeating decimal (approximately 0.64878, or 64.878%).

133 ÷ 205 = 0.64878 (64.878%)
