Exact Answer

==================================================
Problem: What is 3/49 plus 2/9?
Formula / Expression: 3/49 + 2/9
Final Answer: 125/441
==================================================

Step-by-Step Solution:

Step 1: Find the Least Common Denominator (LCD)
The denominators 49 and 9 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 49 × 9 = 441.
Working: LCD(49, 9) = 441

Step 2: Convert to Equivalent Fractions with Common Denominator 441
Multiply the numerator and denominator of 3/49 by 9, and multiply the numerator and denominator of 2/9 by 49 so both fractions share the common base 441.
Working: 3 × 9/49 × 9 = 27/441 and 2 × 49/9 × 49 = 98/441

Step 3: Add the Numerators
Now add the numerators (27 + 98 = 125) and keep the common denominator 441 unchanged.
Working: 27 + 98/441 = 125/441

Step 4: Check if the Fraction Can Be Simplified
The Greatest Common Divisor (GCD) of 125 and 441 is 1, confirming that 125/441 cannot be reduced further—it is already in its simplest irreducible form.
Working: 125/441

Step 5: Decimal & Percentage Representation
Dividing the numerator 125 by denominator 441 produces a repeating decimal (approximately 0.283447, or 28.3447%).
Working: 125 ÷ 441 = 0.283447 (28.3447%)

Key Values:
- Simplified Fraction: 125/441
- Mixed Number Form: 125/441
- Decimal Value: 0.283447

The denominators 49 and 9 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 49 × 9 = 441.

LCD(49, 9) = 441

Step 2

Convert to Equivalent Fractions with Common Denominator 441

Multiply the numerator and denominator of 3/49 by 9, and multiply the numerator and denominator of 2/9 by 49 so both fractions share the common base 441.

3 × 9/49 × 9 = 27/441 and 2 × 49/9 × 49 = 98/441

Step 3

Add the Numerators

Now add the numerators (27 + 98 = 125) and keep the common denominator 441 unchanged.

27 + 98/441 = 125/441

Step 4
