What is 2/7 plus 3/6? (Answer: 11/14)

Exact Answer

==================================================
Problem: What is 2/7 plus 3/6?
Formula / Expression: 2/7 + 3/6
Final Answer: 11/14
==================================================

Step-by-Step Solution:

Step 1: Find the Least Common Denominator (LCD)
The denominators 7 and 6 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 7 × 6 = 42.
Working: LCD(7, 6) = 42

Step 2: Convert to Equivalent Fractions with Common Denominator 42
Multiply the numerator and denominator of 2/7 by 6, and multiply the numerator and denominator of 3/6 by 7 so both fractions share the common base 42.
Working: 2 × 6/7 × 6 = 12/42 and 3 × 7/6 × 7 = 21/42

Step 3: Add the Numerators
Now add the numerators (12 + 21 = 33) and keep the common denominator 42 unchanged.
Working: 12 + 21/42 = 33/42

Step 4: Simplify the Fraction to Lowest Terms
Find the Greatest Common Divisor (GCD) of 33 and 42, which is 3. Divide both the numerator and denominator by 3.
Working: 33 ÷ 3/42 ÷ 3 = 11/14

Step 5: Decimal & Percentage Representation
Dividing the numerator 11 by denominator 14 produces a repeating decimal (approximately 0.785714, or 78.5714%).
Working: 11 ÷ 14 = 0.785714 (78.5714%)

Key Values:
- Simplified Fraction: 11/14
- Mixed Number Form: 11/14
- Decimal Value: 0.785714
- Percentage: 78.5714%

Step-by-Step Solution: 2/7 + 3/6

Step 1

Find the Least Common Denominator (LCD)

The denominators 7 and 6 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 7 × 6 = 42.

LCD(7, 6) = 42

Step 2

Convert to Equivalent Fractions with Common Denominator 42

Multiply the numerator and denominator of 2/7 by 6, and multiply the numerator and denominator of 3/6 by 7 so both fractions share the common base 42.

2 × 6/7 × 6 = 12/42 and 3 × 7/6 × 7 = 21/42

Step 3

Add the Numerators

Now add the numerators (12 + 21 = 33) and keep the common denominator 42 unchanged.

12 + 21/42 = 33/42

Step 4

Simplify the Fraction to Lowest Terms

Find the Greatest Common Divisor (GCD) of 33 and 42, which is 3. Divide both the numerator and denominator by 3.

33 ÷ 3/42 ÷ 3 = 11/14

Step 5

Decimal & Percentage Representation

Dividing the numerator 11 by denominator 14 produces a repeating decimal (approximately 0.785714, or 78.5714%).

11 ÷ 14 = 0.785714 (78.5714%)
