What is 2/41 plus 3/7? (Answer: 137/287)

Exact Answer

==================================================
Problem: What is 2/41 plus 3/7?
Formula / Expression: 2/41 + 3/7
Final Answer: 137/287
==================================================

Step-by-Step Solution:

Step 1: Find the Least Common Denominator (LCD)
The denominators 41 and 7 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 41 × 7 = 287.
Working: LCD(41, 7) = 287

Step 2: Convert to Equivalent Fractions with Common Denominator 287
Multiply the numerator and denominator of 2/41 by 7, and multiply the numerator and denominator of 3/7 by 41 so both fractions share the common base 287.
Working: 2 × 7/41 × 7 = 14/287 and 3 × 41/7 × 41 = 123/287

Step 3: Add the Numerators
Now add the numerators (14 + 123 = 137) and keep the common denominator 287 unchanged.
Working: 14 + 123/287 = 137/287

Step 4: Check if the Fraction Can Be Simplified
The Greatest Common Divisor (GCD) of 137 and 287 is 1, confirming that 137/287 cannot be reduced further—it is already in its simplest irreducible form.
Working: 137/287

Step 5: Decimal & Percentage Representation
Dividing the numerator 137 by denominator 287 produces a repeating decimal (approximately 0.477352, or 47.7352%).
Working: 137 ÷ 287 = 0.477352 (47.7352%)

Key Values:
- Simplified Fraction: 137/287
- Mixed Number Form: 137/287
- Decimal Value: 0.477352
- Percentage: 47.7352%

Step-by-Step Solution: 2/41 + 3/7

Step 1

Find the Least Common Denominator (LCD)

The denominators 41 and 7 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 41 × 7 = 287.

LCD(41, 7) = 287

Step 2

Convert to Equivalent Fractions with Common Denominator 287

Multiply the numerator and denominator of 2/41 by 7, and multiply the numerator and denominator of 3/7 by 41 so both fractions share the common base 287.

2 × 7/41 × 7 = 14/287 and 3 × 41/7 × 41 = 123/287

Step 3

Add the Numerators

Now add the numerators (14 + 123 = 137) and keep the common denominator 287 unchanged.

14 + 123/287 = 137/287

Step 4

Check if the Fraction Can Be Simplified

The Greatest Common Divisor (GCD) of 137 and 287 is 1, confirming that 137/287 cannot be reduced further—it is already in its simplest irreducible form.
