Exact Answer

==================================================
Problem: What is 2/23 plus 5/8?
Formula / Expression: 2/23 + 5/8
Final Answer: 131/184
==================================================

Step-by-Step Solution:

Step 1: Find the Least Common Denominator (LCD)
The denominators 23 and 8 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 23 × 8 = 184.
Working: LCD(23, 8) = 184

Step 2: Convert to Equivalent Fractions with Common Denominator 184
Multiply the numerator and denominator of 2/23 by 8, and multiply the numerator and denominator of 5/8 by 23 so both fractions share the common base 184.
Working: 2 × 8/23 × 8 = 16/184 and 5 × 23/8 × 23 = 115/184

Step 3: Add the Numerators
Now add the numerators (16 + 115 = 131) and keep the common denominator 184 unchanged.
Working: 16 + 115/184 = 131/184

Step 4: Check if the Fraction Can Be Simplified
The Greatest Common Divisor (GCD) of 131 and 184 is 1, confirming that 131/184 cannot be reduced further—it is already in its simplest irreducible form.
Working: 131/184

Step 5: Decimal & Percentage Representation
Dividing the numerator 131 by denominator 184 produces a repeating decimal (approximately 0.711957, or 71.1957%).
Working: 131 ÷ 184 = 0.711957 (71.1957%)

Key Values:
- Simplified Fraction: 131/184
- Mixed Number Form: 131/184
- Decimal Value: 0.711957
- Percentage: 71.1957%

Step-by-Step Solution: 2/23 + 5/8

Step 1

Find the Least Common Denominator (LCD)

The denominators 23 and 8 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 23 × 8 = 184.

LCD(23, 8) = 184

Step 2

Convert to Equivalent Fractions with Common Denominator 184

Multiply the numerator and denominator of 2/23 by 8, and multiply the numerator and denominator of 5/8 by 23 so both fractions share the common base 184.

2 × 8/23 × 8 = 16/184 and 5 × 23/8 × 23 = 115/184

Step 3

Add the Numerators

Now add the numerators (16 + 115 = 131) and keep the common denominator 184 unchanged.

16 + 115/184 = 131/184

Step 4

Check if the Fraction Can Be Simplified

The Greatest Common Divisor (GCD) of 131 and 184 is 1, confirming that 131/184 cannot be reduced further—it is already in its simplest irreducible form.
