Exact Answer

==================================================
Problem: What is 2/13 plus 4/23?
Formula / Expression: 2/13 + 4/23
Final Answer: 98/299
==================================================

Step-by-Step Solution:

Step 1: Find the Least Common Denominator (LCD)
The denominators 13 and 23 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 13 × 23 = 299.
Working: LCD(13, 23) = 299

Step 2: Convert to Equivalent Fractions with Common Denominator 299
Multiply the numerator and denominator of 2/13 by 23, and multiply the numerator and denominator of 4/23 by 13 so both fractions share the common base 299.
Working: 2 × 23/13 × 23 = 46/299 and 4 × 13/23 × 13 = 52/299

Step 3: Add the Numerators
Now add the numerators (46 + 52 = 98) and keep the common denominator 299 unchanged.
Working: 46 + 52/299 = 98/299

Step 4: Check if the Fraction Can Be Simplified
The Greatest Common Divisor (GCD) of 98 and 299 is 1, confirming that 98/299 cannot be reduced further—it is already in its simplest irreducible form.
Working: 98/299

Step 5: Decimal & Percentage Representation
Dividing the numerator 98 by denominator 299 produces a repeating decimal (approximately 0.327759, or 32.7759%).
Working: 98 ÷ 299 = 0.327759 (32.7759%)

Key Values:
- Simplified Fraction: 98/299
- Mixed Number Form: 98/299
- Decimal Value: 0.327759
- Percentage: 32.7759%

Step-by-Step Solution: 2/13 + 4/23

Step 1

Find the Least Common Denominator (LCD)

The denominators 13 and 23 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 13 × 23 = 299.

LCD(13, 23) = 299

Step 2

Convert to Equivalent Fractions with Common Denominator 299

Multiply the numerator and denominator of 2/13 by 23, and multiply the numerator and denominator of 4/23 by 13 so both fractions share the common base 299.

2 × 23/13 × 23 = 46/299 and 4 × 13/23 × 13 = 52/299

Step 3

Add the Numerators

Now add the numerators (46 + 52 = 98) and keep the common denominator 299 unchanged.

46 + 52/299 = 98/299

Step 4

Check if the Fraction Can Be Simplified

The Greatest Common Divisor (GCD) of 98 and 299 is 1, confirming that 98/299 cannot be reduced further—it is already in its simplest irreducible form.
