What is 2/7 plus 6/20? (Answer: 41/70)

Exact Answer

==================================================
Problem: What is 2/7 plus 6/20?
Formula / Expression: 2/7 + 6/20
Final Answer: 41/70
==================================================

Step-by-Step Solution:

Step 1: Find the Least Common Denominator (LCD)
The denominators 7 and 20 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 7 × 20 = 140.
Working: LCD(7, 20) = 140

Step 2: Convert to Equivalent Fractions with Common Denominator 140
Multiply the numerator and denominator of 2/7 by 20, and multiply the numerator and denominator of 6/20 by 7 so both fractions share the common base 140.
Working: 2 × 20/7 × 20 = 40/140 and 6 × 7/20 × 7 = 42/140

Step 3: Add the Numerators
Now add the numerators (40 + 42 = 82) and keep the common denominator 140 unchanged.
Working: 40 + 42/140 = 82/140

Step 4: Simplify the Fraction to Lowest Terms
Find the Greatest Common Divisor (GCD) of 82 and 140, which is 2. Divide both the numerator and denominator by 2.
Working: 82 ÷ 2/140 ÷ 2 = 41/70

Step 5: Decimal & Percentage Representation
Dividing the numerator 41 by denominator 70 produces a repeating decimal (approximately 0.585714, or 58.5714%).
Working: 41 ÷ 70 = 0.585714 (58.5714%)

Key Values:
- Simplified Fraction: 41/70
- Mixed Number Form: 41/70
- Decimal Value: 0.585714
- Percentage: 58.5714%

Step-by-Step Solution: 2/7 + 6/20

Step 1

Find the Least Common Denominator (LCD)

The denominators 7 and 20 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 7 × 20 = 140.

LCD(7, 20) = 140

Step 2

Convert to Equivalent Fractions with Common Denominator 140

Multiply the numerator and denominator of 2/7 by 20, and multiply the numerator and denominator of 6/20 by 7 so both fractions share the common base 140.

2 × 20/7 × 20 = 40/140 and 6 × 7/20 × 7 = 42/140

Step 3

Add the Numerators

Now add the numerators (40 + 42 = 82) and keep the common denominator 140 unchanged.

40 + 42/140 = 82/140

Step 4

Simplify the Fraction to Lowest Terms

Find the Greatest Common Divisor (GCD) of 82 and 140, which is 2. Divide both the numerator and denominator by 2.

82 ÷ 2/140 ÷ 2 = 41/70

Step 5

Decimal & Percentage Representation

Dividing the numerator 41 by denominator 70 produces a repeating decimal (approximately 0.585714, or 58.5714%).

41 ÷ 70 = 0.585714 (58.5714%)
