Exact Answer

==================================================
Problem: What is 2/14 plus 2/9?
Formula / Expression: 2/14 + 2/9
Final Answer: 23/63
==================================================

Step-by-Step Solution:

Step 1: Find the Least Common Denominator (LCD)
The denominators 14 and 9 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 14 × 9 = 126.
Working: LCD(14, 9) = 126

Step 2: Convert to Equivalent Fractions with Common Denominator 126
Multiply the numerator and denominator of 2/14 by 9, and multiply the numerator and denominator of 2/9 by 14 so both fractions share the common base 126.
Working: 2 × 9/14 × 9 = 18/126 and 2 × 14/9 × 14 = 28/126

Step 3: Add the Numerators
Now add the numerators (18 + 28 = 46) and keep the common denominator 126 unchanged.
Working: 18 + 28/126 = 46/126

Step 4: Simplify the Fraction to Lowest Terms
Find the Greatest Common Divisor (GCD) of 46 and 126, which is 2. Divide both the numerator and denominator by 2.
Working: 46 ÷ 2/126 ÷ 2 = 23/63

Step 5: Decimal & Percentage Representation
Dividing the numerator 23 by denominator 63 produces a repeating decimal (approximately 0.365079, or 36.5079%).
Working: 23 ÷ 63 = 0.365079 (36.5079%)

Key Values:
- Simplified Fraction: 23/63
- Mixed Number Form: 23/63
- Decimal Value: 0.365079
- Percentage: 36.5079%

Step-by-Step Solution: 2/14 + 2/9

Step 1

Find the Least Common Denominator (LCD)

The denominators 14 and 9 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 14 × 9 = 126.

LCD(14, 9) = 126

Step 2

Convert to Equivalent Fractions with Common Denominator 126

Multiply the numerator and denominator of 2/14 by 9, and multiply the numerator and denominator of 2/9 by 14 so both fractions share the common base 126.

2 × 9/14 × 9 = 18/126 and 2 × 14/9 × 14 = 28/126

Step 3

Add the Numerators

Now add the numerators (18 + 28 = 46) and keep the common denominator 126 unchanged.

18 + 28/126 = 46/126

Step 4

Simplify the Fraction to Lowest Terms

Find the Greatest Common Divisor (GCD) of 46 and 126, which is 2. Divide both the numerator and denominator by 2.

46 ÷ 2/126 ÷ 2 = 23/63

Step 5

Decimal & Percentage Representation

Dividing the numerator 23 by denominator 63 produces a repeating decimal (approximately 0.365079, or 36.5079%).

23 ÷ 63 = 0.365079 (36.5079%)
