What is 2/14 plus 1/3? (Answer: 10/21)

Exact Answer

==================================================
Problem: What is 2/14 plus 1/3?
Formula / Expression: 2/14 + 1/3
Final Answer: 10/21
==================================================

Step-by-Step Solution:

Step 1: Find the Least Common Denominator (LCD)
The denominators 14 and 3 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 14 × 3 = 42.
Working: LCD(14, 3) = 42

Step 2: Convert to Equivalent Fractions with Common Denominator 42
Multiply the numerator and denominator of 2/14 by 3, and multiply the numerator and denominator of 1/3 by 14 so both fractions share the common base 42.
Working: 2 × 3/14 × 3 = 6/42 and 1 × 14/3 × 14 = 14/42

Step 3: Add the Numerators
Now add the numerators (6 + 14 = 20) and keep the common denominator 42 unchanged.
Working: 6 + 14/42 = 20/42

Step 4: Simplify the Fraction to Lowest Terms
Find the Greatest Common Divisor (GCD) of 20 and 42, which is 2. Divide both the numerator and denominator by 2.
Working: 20 ÷ 2/42 ÷ 2 = 10/21

Step 5: Decimal & Percentage Representation
Dividing the numerator 10 by denominator 21 produces a repeating decimal (approximately 0.47619, or 47.619%).
Working: 10 ÷ 21 = 0.47619 (47.619%)

Key Values:
- Simplified Fraction: 10/21
- Mixed Number Form: 10/21
- Decimal Value: 0.47619
- Percentage: 47.619%

Step-by-Step Solution: 2/14 + 1/3

Step 1

Find the Least Common Denominator (LCD)

The denominators 14 and 3 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 14 × 3 = 42.

LCD(14, 3) = 42

Step 2

Convert to Equivalent Fractions with Common Denominator 42

Multiply the numerator and denominator of 2/14 by 3, and multiply the numerator and denominator of 1/3 by 14 so both fractions share the common base 42.

2 × 3/14 × 3 = 6/42 and 1 × 14/3 × 14 = 14/42

Step 3

Add the Numerators

Now add the numerators (6 + 14 = 20) and keep the common denominator 42 unchanged.

6 + 14/42 = 20/42

Step 4

Simplify the Fraction to Lowest Terms

Find the Greatest Common Divisor (GCD) of 20 and 42, which is 2. Divide both the numerator and denominator by 2.

20 ÷ 2/42 ÷ 2 = 10/21

Step 5

Decimal & Percentage Representation

Dividing the numerator 10 by denominator 21 produces a repeating decimal (approximately 0.47619, or 47.619%).

10 ÷ 21 = 0.47619 (47.619%)
