Exact Answer

==================================================
Problem: What is 2/13 plus 9/49?
Formula / Expression: 2/13 + 9/49
Final Answer: 215/637
==================================================

Step-by-Step Solution:

Step 1: Find the Least Common Denominator (LCD)
The denominators 13 and 49 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 13 × 49 = 637.
Working: LCD(13, 49) = 637

Step 2: Convert to Equivalent Fractions with Common Denominator 637
Multiply the numerator and denominator of 2/13 by 49, and multiply the numerator and denominator of 9/49 by 13 so both fractions share the common base 637.
Working: 2 × 49/13 × 49 = 98/637 and 9 × 13/49 × 13 = 117/637

Step 3: Add the Numerators
Now add the numerators (98 + 117 = 215) and keep the common denominator 637 unchanged.
Working: 98 + 117/637 = 215/637

Step 4: Check if the Fraction Can Be Simplified
The Greatest Common Divisor (GCD) of 215 and 637 is 1, confirming that 215/637 cannot be reduced further—it is already in its simplest irreducible form.
Working: 215/637

Step 5: Decimal & Percentage Representation
Dividing the numerator 215 by denominator 637 produces a repeating decimal (approximately 0.33752, or 33.752%).
Working: 215 ÷ 637 = 0.33752 (33.752%)

Key Values:
- Simplified Fraction: 215/637
- Mixed Number Form: 215/637
- Decimal Value: 0.33752
- Percentage: 33.752%

Step-by-Step Solution: 2/13 + 9/49

Step 1

Find the Least Common Denominator (LCD)

The denominators 13 and 49 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 13 × 49 = 637.

LCD(13, 49) = 637

Step 2

Convert to Equivalent Fractions with Common Denominator 637

Multiply the numerator and denominator of 2/13 by 49, and multiply the numerator and denominator of 9/49 by 13 so both fractions share the common base 637.

2 × 49/13 × 49 = 98/637 and 9 × 13/49 × 13 = 117/637

Step 3

Add the Numerators

Now add the numerators (98 + 117 = 215) and keep the common denominator 637 unchanged.

98 + 117/637 = 215/637

Step 4

Check if the Fraction Can Be Simplified

The Greatest Common Divisor (GCD) of 215 and 637 is 1, confirming that 215/637 cannot be reduced further—it is already in its simplest irreducible form.
