What is 2/8 plus 1/3? (Answer: 7/12)

Exact Answer

==================================================
Problem: What is 2/8 plus 1/3?
Formula / Expression: 2/8 + 1/3
Final Answer: 7/12
==================================================

Step-by-Step Solution:

Step 1: Find the Least Common Denominator (LCD)
The denominators 8 and 3 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 8 × 3 = 24.
Working: LCD(8, 3) = 24

Step 2: Convert to Equivalent Fractions with Common Denominator 24
Multiply the numerator and denominator of 2/8 by 3, and multiply the numerator and denominator of 1/3 by 8 so both fractions share the common base 24.
Working: 2 × 3/8 × 3 = 6/24 and 1 × 8/3 × 8 = 8/24

Step 3: Add the Numerators
Now add the numerators (6 + 8 = 14) and keep the common denominator 24 unchanged.
Working: 6 + 8/24 = 14/24

Step 4: Simplify the Fraction to Lowest Terms
Find the Greatest Common Divisor (GCD) of 14 and 24, which is 2. Divide both the numerator and denominator by 2.
Working: 14 ÷ 2/24 ÷ 2 = 7/12

Step 5: Decimal & Percentage Representation
Dividing the numerator 7 by denominator 12 produces a repeating decimal (approximately 0.583333, or 58.3333%).
Working: 7 ÷ 12 = 0.583333 (58.3333%)

Key Values:
- Simplified Fraction: 7/12
- Mixed Number Form: 7/12
- Decimal Value: 0.583333
- Percentage: 58.3333%

Find the Least Common Denominator (LCD)

The denominators 8 and 3 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 8 × 3 = 24.

LCD(8, 3) = 24

Step 2

Convert to Equivalent Fractions with Common Denominator 24

Multiply the numerator and denominator of 2/8 by 3, and multiply the numerator and denominator of 1/3 by 8 so both fractions share the common base 24.

2 × 3/8 × 3 = 6/24 and 1 × 8/3 × 8 = 8/24

Step 3

Add the Numerators

Now add the numerators (6 + 8 = 14) and keep the common denominator 24 unchanged.

6 + 8/24 = 14/24

Step 4

Simplify the Fraction to Lowest Terms

Find the Greatest Common Divisor (GCD) of 14 and 24, which is 2. Divide both the numerator and denominator by 2.

14 ÷ 2/24 ÷ 2 = 7/12

Step 5

Decimal & Percentage Representation

Dividing the numerator 7 by denominator 12 produces a repeating decimal (approximately 0.583333, or 58.3333%).
