What is 2/12 plus 4/8? (Answer: 2/3)

Exact Answer

==================================================
Problem: What is 2/12 plus 4/8?
Formula / Expression: 2/12 + 4/8
Final Answer: 2/3
==================================================

Step-by-Step Solution:

Step 1: Find the Least Common Denominator (LCD)
The denominators 12 and 8 share a common factor (GCD = 4). Finding their Least Common Multiple gives an LCD of 24 (which is smaller than their product 12 × 8 = 96, keeping the calculation simpler).
Working: LCD(12, 8) = 24

Step 2: Convert to Equivalent Fractions with Common Denominator 24
Multiply the numerator and denominator of 2/12 by 2, and multiply the numerator and denominator of 4/8 by 3 so both fractions share the common base 24.
Working: 2 × 2/12 × 2 = 4/24 and 4 × 3/8 × 3 = 12/24

Step 3: Add the Numerators
Now add the numerators (4 + 12 = 16) and keep the common denominator 24 unchanged.
Working: 4 + 12/24 = 16/24

Step 4: Simplify the Fraction to Lowest Terms
Find the Greatest Common Divisor (GCD) of 16 and 24, which is 8. Divide both the numerator and denominator by 8.
Working: 16 ÷ 8/24 ÷ 8 = 2/3

Step 5: Decimal & Percentage Representation
Dividing the numerator 2 by denominator 3 produces a repeating decimal (approximately 0.666667, or 66.6667%).
Working: 2 ÷ 3 = 0.666667 (66.6667%)

Key Values:
- Simplified Fraction: 2/3
- Mixed Number Form: 2/3
- Decimal Value: 0.666667
- Percentage: 66.6667%

Step-by-Step Solution: 2/12 + 4/8

Step 1

Find the Least Common Denominator (LCD)

The denominators 12 and 8 share a common factor (GCD = 4). Finding their Least Common Multiple gives an LCD of 24 (which is smaller than their product 12 × 8 = 96, keeping the calculation simpler).

LCD(12, 8) = 24

Step 2

Convert to Equivalent Fractions with Common Denominator 24

Multiply the numerator and denominator of 2/12 by 2, and multiply the numerator and denominator of 4/8 by 3 so both fractions share the common base 24.

2 × 2/12 × 2 = 4/24 and 4 × 3/8 × 3 = 12/24

Step 3

Add the Numerators

Now add the numerators (4 + 12 = 16) and keep the common denominator 24 unchanged.

4 + 12/24 = 16/24

Step 4

Simplify the Fraction to Lowest Terms

Find the Greatest Common Divisor (GCD) of 16 and 24, which is 8. Divide both the numerator and denominator by 8.

16 ÷ 8/24 ÷ 8 = 2/3

Step 5

Decimal & Percentage Representation

Dividing the numerator 2 by denominator 3 produces a repeating decimal (approximately 0.666667, or 66.6667%).

2 ÷ 3 = 0.666667 (66.6667%)
