Exact Answer

==================================================
Problem: What is 2/17 plus 2/8?
Formula / Expression: 2/17 + 2/8
Final Answer: 25/68
==================================================

Step-by-Step Solution:

Step 1: Find the Least Common Denominator (LCD)
The denominators 17 and 8 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 17 × 8 = 136.
Working: LCD(17, 8) = 136

Step 2: Convert to Equivalent Fractions with Common Denominator 136
Multiply the numerator and denominator of 2/17 by 8, and multiply the numerator and denominator of 2/8 by 17 so both fractions share the common base 136.
Working: 2 × 8/17 × 8 = 16/136 and 2 × 17/8 × 17 = 34/136

Step 3: Add the Numerators
Now add the numerators (16 + 34 = 50) and keep the common denominator 136 unchanged.
Working: 16 + 34/136 = 50/136

Step 4: Simplify the Fraction to Lowest Terms
Find the Greatest Common Divisor (GCD) of 50 and 136, which is 2. Divide both the numerator and denominator by 2.
Working: 50 ÷ 2/136 ÷ 2 = 25/68

Step 5: Decimal & Percentage Representation
Dividing the numerator 25 by denominator 68 produces a repeating decimal (approximately 0.367647, or 36.7647%).
Working: 25 ÷ 68 = 0.367647 (36.7647%)

Key Values:
- Simplified Fraction: 25/68
- Mixed Number Form: 25/68
- Decimal Value: 0.367647
- Percentage: 36.7647%

Step-by-Step Solution: 2/17 + 2/8

Step 1

Find the Least Common Denominator (LCD)

The denominators 17 and 8 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 17 × 8 = 136.

LCD(17, 8) = 136

Step 2

Convert to Equivalent Fractions with Common Denominator 136

Multiply the numerator and denominator of 2/17 by 8, and multiply the numerator and denominator of 2/8 by 17 so both fractions share the common base 136.

2 × 8/17 × 8 = 16/136 and 2 × 17/8 × 17 = 34/136

Step 3

Add the Numerators

Now add the numerators (16 + 34 = 50) and keep the common denominator 136 unchanged.

16 + 34/136 = 50/136

Step 4

Simplify the Fraction to Lowest Terms

Find the Greatest Common Divisor (GCD) of 50 and 136, which is 2. Divide both the numerator and denominator by 2.

50 ÷ 2/136 ÷ 2 = 25/68

Step 5

Decimal & Percentage Representation

Dividing the numerator 25 by denominator 68 produces a repeating decimal (approximately 0.367647, or 36.7647%).

25 ÷ 68 = 0.367647 (36.7647%)
