What is 2/14 plus 4/7? (Answer: 5/7)

Exact Answer

==================================================
Problem: What is 2/14 plus 4/7?
Formula / Expression: 2/14 + 4/7
Final Answer: 5/7
==================================================

Step-by-Step Solution:

Step 1: Find the Least Common Denominator (LCD)
Notice that 14 is an exact multiple of 7 (7 × 2 = 14). The Least Common Denominator (LCD) is simply 14, meaning we only need to scale one fraction.
Working: LCD(14, 7) = 14

Step 2: Convert to Equivalent Fractions with Common Denominator 14
Multiply the numerator and denominator of 2/14 by 1, and multiply the numerator and denominator of 4/7 by 2 so both fractions share the common base 14.
Working: 2 × 1/14 × 1 = 2/14 and 4 × 2/7 × 2 = 8/14

Step 3: Add the Numerators
Now add the numerators (2 + 8 = 10) and keep the common denominator 14 unchanged.
Working: 2 + 8/14 = 10/14

Step 4: Simplify the Fraction to Lowest Terms
Find the Greatest Common Divisor (GCD) of 10 and 14, which is 2. Divide both the numerator and denominator by 2.
Working: 10 ÷ 2/14 ÷ 2 = 5/7

Step 5: Decimal & Percentage Representation
Dividing the numerator 5 by denominator 7 produces a repeating decimal (approximately 0.714286, or 71.4286%).
Working: 5 ÷ 7 = 0.714286 (71.4286%)

Key Values:
- Simplified Fraction: 5/7
- Mixed Number Form: 5/7
- Decimal Value: 0.714286
- Percentage: 71.4286%
