Exact Answer

==================================================
Problem: What is 4/23 plus 2/8?
Formula / Expression: 4/23 + 2/8
Final Answer: 39/92
==================================================

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 4/23 by 8, and multiply the numerator and denominator of 2/8 by 23 so both fractions share the common base 184.
Working: 4 × 8/23 × 8 = 32/184 and 2 × 23/8 × 23 = 46/184

Step 3: Add the Numerators
Now add the numerators (32 + 46 = 78) and keep the common denominator 184 unchanged.
Working: 32 + 46/184 = 78/184

Step 4: Simplify the Fraction to Lowest Terms
Find the Greatest Common Divisor (GCD) of 78 and 184, which is 2. Divide both the numerator and denominator by 2.
Working: 78 ÷ 2/184 ÷ 2 = 39/92

Step 5: Decimal & Percentage Representation
Dividing the numerator 39 by denominator 92 produces a repeating decimal (approximately 0.423913, or 42.3913%).
Working: 39 ÷ 92 = 0.423913 (42.3913%)

Key Values:
- Simplified Fraction: 39/92
- Mixed Number Form: 39/92
- Decimal Value: 0.423913
- Percentage: 42.3913%

Step-by-Step Solution: 4/23 + 2/8

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 4/23 by 8, and multiply the numerator and denominator of 2/8 by 23 so both fractions share the common base 184.

4 × 8/23 × 8 = 32/184 and 2 × 23/8 × 23 = 46/184

Step 3

Add the Numerators

Now add the numerators (32 + 46 = 78) and keep the common denominator 184 unchanged.

32 + 46/184 = 78/184

Step 4

Simplify the Fraction to Lowest Terms

Find the Greatest Common Divisor (GCD) of 78 and 184, which is 2. Divide both the numerator and denominator by 2.

78 ÷ 2/184 ÷ 2 = 39/92

Step 5

Decimal & Percentage Representation

Dividing the numerator 39 by denominator 92 produces a repeating decimal (approximately 0.423913, or 42.3913%).

39 ÷ 92 = 0.423913 (42.3913%)
