What is 3/41 plus 2/5? (Answer: 97/205)

Exact Answer

==================================================
Problem: What is 3/41 plus 2/5?
Formula / Expression: 3/41 + 2/5
Final Answer: 97/205
==================================================

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 3/41 by 5, and multiply the numerator and denominator of 2/5 by 41 so both fractions share the common base 205.
Working: 3 × 5/41 × 5 = 15/205 and 2 × 41/5 × 41 = 82/205

Step 3: Add the Numerators
Now add the numerators (15 + 82 = 97) and keep the common denominator 205 unchanged.
Working: 15 + 82/205 = 97/205

Step 4: Check if the Fraction Can Be Simplified
The Greatest Common Divisor (GCD) of 97 and 205 is 1, confirming that 97/205 cannot be reduced further—it is already in its simplest irreducible form.
Working: 97/205

Step 5: Decimal & Percentage Representation
Dividing the numerator 97 by denominator 205 produces a repeating decimal (approximately 0.473171, or 47.3171%).
Working: 97 ÷ 205 = 0.473171 (47.3171%)

Key Values:
- Simplified Fraction: 97/205
- Mixed Number Form: 97/205
- Decimal Value: 0.473171
- Percentage: 47.3171%

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

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

3 × 5/41 × 5 = 15/205 and 2 × 41/5 × 41 = 82/205

Step 3

Add the Numerators

Now add the numerators (15 + 82 = 97) and keep the common denominator 205 unchanged.

15 + 82/205 = 97/205

Step 4

Check if the Fraction Can Be Simplified

The Greatest Common Divisor (GCD) of 97 and 205 is 1, confirming that 97/205 cannot be reduced further—it is already in its simplest irreducible form.

97/205

Step 5

Decimal & Percentage Representation

Dividing the numerator 97 by denominator 205 produces a repeating decimal (approximately 0.473171, or 47.3171%).
