Exact Answer

==================================================
Problem: What is 2/35 plus 3/9?
Formula / Expression: 2/35 + 3/9
Final Answer: 41/105
==================================================

Step-by-Step Solution:

Step 1: Find the Least Common Denominator (LCD)
The denominators 35 and 9 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 35 × 9 = 315.
Working: LCD(35, 9) = 315

Step 2: Convert to Equivalent Fractions with Common Denominator 315
Multiply the numerator and denominator of 2/35 by 9, and multiply the numerator and denominator of 3/9 by 35 so both fractions share the common base 315.
Working: 2 × 9/35 × 9 = 18/315 and 3 × 35/9 × 35 = 105/315

Step 3: Add the Numerators
Now add the numerators (18 + 105 = 123) and keep the common denominator 315 unchanged.
Working: 18 + 105/315 = 123/315

Step 4: Simplify the Fraction to Lowest Terms
Find the Greatest Common Divisor (GCD) of 123 and 315, which is 3. Divide both the numerator and denominator by 3.
Working: 123 ÷ 3/315 ÷ 3 = 41/105

Step 5: Decimal & Percentage Representation
Dividing the numerator 41 by denominator 105 produces a repeating decimal (approximately 0.390476, or 39.0476%).
Working: 41 ÷ 105 = 0.390476 (39.0476%)

Key Values:
- Simplified Fraction: 41/105
- Mixed Number Form: 41/105
- Decimal Value: 0.390476
- Percentage: 39.0476%

Step-by-Step Solution: 2/35 + 3/9

Step 1

Find the Least Common Denominator (LCD)

The denominators 35 and 9 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 35 × 9 = 315.

LCD(35, 9) = 315

Step 2

Convert to Equivalent Fractions with Common Denominator 315

Multiply the numerator and denominator of 2/35 by 9, and multiply the numerator and denominator of 3/9 by 35 so both fractions share the common base 315.

2 × 9/35 × 9 = 18/315 and 3 × 35/9 × 35 = 105/315

Step 3

Add the Numerators

Now add the numerators (18 + 105 = 123) and keep the common denominator 315 unchanged.

18 + 105/315 = 123/315

Step 4

Simplify the Fraction to Lowest Terms

Find the Greatest Common Divisor (GCD) of 123 and 315, which is 3. Divide both the numerator and denominator by 3.

123 ÷ 3/315 ÷ 3 = 41/105

Step 5

Decimal & Percentage Representation

Dividing the numerator 41 by denominator 105 produces a repeating decimal (approximately 0.390476, or 39.0476%).

41 ÷ 105 = 0.390476 (39.0476%)
