Exact Answer

==================================================
Problem: What is 2/15 plus 2/14?
Formula / Expression: 2/15 + 2/14
Final Answer: 29/105
==================================================

Step-by-Step Solution:

Step 1: Find the Least Common Denominator (LCD)
The denominators 15 and 14 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 15 × 14 = 210.
Working: LCD(15, 14) = 210

Step 2: Convert to Equivalent Fractions with Common Denominator 210
Multiply the numerator and denominator of 2/15 by 14, and multiply the numerator and denominator of 2/14 by 15 so both fractions share the common base 210.
Working: 2 × 14/15 × 14 = 28/210 and 2 × 15/14 × 15 = 30/210

Step 3: Add the Numerators
Now add the numerators (28 + 30 = 58) and keep the common denominator 210 unchanged.
Working: 28 + 30/210 = 58/210

Step 4: Simplify the Fraction to Lowest Terms
Find the Greatest Common Divisor (GCD) of 58 and 210, which is 2. Divide both the numerator and denominator by 2.
Working: 58 ÷ 2/210 ÷ 2 = 29/105

Step 5: Decimal & Percentage Representation
Dividing the numerator 29 by denominator 105 produces a repeating decimal (approximately 0.27619, or 27.619%).
Working: 29 ÷ 105 = 0.27619 (27.619%)

Key Values:
- Simplified Fraction: 29/105
- Mixed Number Form: 29/105
- Decimal Value: 0.27619
- Percentage: 27.619%

Step-by-Step Solution: 2/15 + 2/14

Step 1

Find the Least Common Denominator (LCD)

The denominators 15 and 14 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 15 × 14 = 210.

LCD(15, 14) = 210

Step 2

Convert to Equivalent Fractions with Common Denominator 210

Multiply the numerator and denominator of 2/15 by 14, and multiply the numerator and denominator of 2/14 by 15 so both fractions share the common base 210.

2 × 14/15 × 14 = 28/210 and 2 × 15/14 × 15 = 30/210

Step 3

Add the Numerators

Now add the numerators (28 + 30 = 58) and keep the common denominator 210 unchanged.

28 + 30/210 = 58/210

Step 4

Simplify the Fraction to Lowest Terms

Find the Greatest Common Divisor (GCD) of 58 and 210, which is 2. Divide both the numerator and denominator by 2.

58 ÷ 2/210 ÷ 2 = 29/105

Step 5

Decimal & Percentage Representation

Dividing the numerator 29 by denominator 105 produces a repeating decimal (approximately 0.27619, or 27.619%).

29 ÷ 105 = 0.27619 (27.619%)
