Exact Answer

==================================================
Problem: What is 7/41 plus 2/9?
Formula / Expression: 7/41 + 2/9
Final Answer: 145/369
==================================================

Step-by-Step Solution:

Step 1: Find the Least Common Denominator (LCD)
The denominators 41 and 9 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 41 × 9 = 369.
Working: LCD(41, 9) = 369

Step 2: Convert to Equivalent Fractions with Common Denominator 369
Multiply the numerator and denominator of 7/41 by 9, and multiply the numerator and denominator of 2/9 by 41 so both fractions share the common base 369.
Working: 7 × 9/41 × 9 = 63/369 and 2 × 41/9 × 41 = 82/369

Step 3: Add the Numerators
Now add the numerators (63 + 82 = 145) and keep the common denominator 369 unchanged.
Working: 63 + 82/369 = 145/369

Step 4: Check if the Fraction Can Be Simplified
The Greatest Common Divisor (GCD) of 145 and 369 is 1, confirming that 145/369 cannot be reduced further—it is already in its simplest irreducible form.
Working: 145/369

Step 5: Decimal & Percentage Representation
Dividing the numerator 145 by denominator 369 produces a repeating decimal (approximately 0.392954, or 39.2954%).
Working: 145 ÷ 369 = 0.392954 (39.2954%)

Key Values:
- Simplified Fraction: 145/369
- Mixed Number Form: 145/369
- Decimal Value: 0.392954

The denominators 41 and 9 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 41 × 9 = 369.

LCD(41, 9) = 369

Step 2

Convert to Equivalent Fractions with Common Denominator 369

Multiply the numerator and denominator of 7/41 by 9, and multiply the numerator and denominator of 2/9 by 41 so both fractions share the common base 369.

7 × 9/41 × 9 = 63/369 and 2 × 41/9 × 41 = 82/369

Step 3

Add the Numerators

Now add the numerators (63 + 82 = 145) and keep the common denominator 369 unchanged.

63 + 82/369 = 145/369

Step 4

Check if the Fraction Can Be Simplified

The Greatest Common Divisor (GCD) of 145 and 369 is 1, confirming that 145/369 cannot be reduced further—it is already in its simplest irreducible form.
