Exact Answer

==================================================
Problem: What is 2/34 plus 9/39?
Formula / Expression: 2/34 + 9/39
Final Answer: 64/221
==================================================

Step-by-Step Solution:

Step 1: Find the Least Common Denominator (LCD)
The denominators 34 and 39 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 34 × 39 = 1326.
Working: LCD(34, 39) = 1326

Step 2: Convert to Equivalent Fractions with Common Denominator 1326
Multiply the numerator and denominator of 2/34 by 39, and multiply the numerator and denominator of 9/39 by 34 so both fractions share the common base 1326.
Working: 2 × 39/34 × 39 = 78/1326 and 9 × 34/39 × 34 = 306/1326

Step 3: Add the Numerators
Now add the numerators (78 + 306 = 384) and keep the common denominator 1326 unchanged.
Working: 78 + 306/1326 = 384/1326

Step 4: Simplify the Fraction to Lowest Terms
Find the Greatest Common Divisor (GCD) of 384 and 1326, which is 6. Divide both the numerator and denominator by 6.
Working: 384 ÷ 6/1326 ÷ 6 = 64/221

Step 5: Decimal & Percentage Representation
Dividing the numerator 64 by denominator 221 produces a repeating decimal (approximately 0.289593, or 28.9593%).
Working: 64 ÷ 221 = 0.289593 (28.9593%)

Key Values:
- Simplified Fraction: 64/221
- Mixed Number Form: 64/221
- Decimal Value: 0.289593
- Percentage: 28.9593%

Step-by-Step Solution: 2/34 + 9/39

Step 1

Find the Least Common Denominator (LCD)

The denominators 34 and 39 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 34 × 39 = 1326.

LCD(34, 39) = 1326

Step 2

Convert to Equivalent Fractions with Common Denominator 1326

Multiply the numerator and denominator of 2/34 by 39, and multiply the numerator and denominator of 9/39 by 34 so both fractions share the common base 1326.

2 × 39/34 × 39 = 78/1326 and 9 × 34/39 × 34 = 306/1326

Step 3

Add the Numerators

Now add the numerators (78 + 306 = 384) and keep the common denominator 1326 unchanged.

78 + 306/1326 = 384/1326

Step 4

Simplify the Fraction to Lowest Terms

Find the Greatest Common Divisor (GCD) of 384 and 1326, which is 6. Divide both the numerator and denominator by 6.

384 ÷ 6/1326 ÷ 6 = 64/221

Step 5

Decimal & Percentage Representation

Dividing the numerator 64 by denominator 221 produces a repeating decimal (approximately 0.289593, or 28.9593%).

64 ÷ 221 = 0.289593 (28.9593%)
