Exact Answer

==================================================
Problem: What is 4/35 plus 2/9?
Formula / Expression: 4/35 + 2/9
Final Answer: 106/315
==================================================

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 4/35 by 9, and multiply the numerator and denominator of 2/9 by 35 so both fractions share the common base 315.
Working: 4 × 9/35 × 9 = 36/315 and 2 × 35/9 × 35 = 70/315

Step 3: Add the Numerators
Now add the numerators (36 + 70 = 106) and keep the common denominator 315 unchanged.
Working: 36 + 70/315 = 106/315

Step 4: Check if the Fraction Can Be Simplified
The Greatest Common Divisor (GCD) of 106 and 315 is 1, confirming that 106/315 cannot be reduced further—it is already in its simplest irreducible form.
Working: 106/315

Step 5: Decimal & Percentage Representation
Dividing the numerator 106 by denominator 315 produces a repeating decimal (approximately 0.336508, or 33.6508%).
Working: 106 ÷ 315 = 0.336508 (33.6508%)

Key Values:
- Simplified Fraction: 106/315
- Mixed Number Form: 106/315
- Decimal Value: 0.336508
- Percentage: 33.6508%

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 4/35 by 9, and multiply the numerator and denominator of 2/9 by 35 so both fractions share the common base 315.

4 × 9/35 × 9 = 36/315 and 2 × 35/9 × 35 = 70/315

Step 3

Add the Numerators

Now add the numerators (36 + 70 = 106) and keep the common denominator 315 unchanged.

36 + 70/315 = 106/315

Step 4

Check if the Fraction Can Be Simplified

The Greatest Common Divisor (GCD) of 106 and 315 is 1, confirming that 106/315 cannot be reduced further—it is already in its simplest irreducible form.
