Exact Answer

==================================================
Problem: What is 2/8 plus 5/17?
Formula / Expression: 2/8 + 5/17
Final Answer: 37/68
==================================================

Step-by-Step Solution:

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

Step 2: Convert to Equivalent Fractions with Common Denominator 136
Multiply the numerator and denominator of 2/8 by 17, and multiply the numerator and denominator of 5/17 by 8 so both fractions share the common base 136.
Working: 2 × 17/8 × 17 = 34/136 and 5 × 8/17 × 8 = 40/136

Step 3: Add the Numerators
Now add the numerators (34 + 40 = 74) and keep the common denominator 136 unchanged.
Working: 34 + 40/136 = 74/136

Step 4: Simplify the Fraction to Lowest Terms
Find the Greatest Common Divisor (GCD) of 74 and 136, which is 2. Divide both the numerator and denominator by 2.
Working: 74 ÷ 2/136 ÷ 2 = 37/68

Step 5: Decimal & Percentage Representation
Dividing the numerator 37 by denominator 68 produces a repeating decimal (approximately 0.544118, or 54.4118%).
Working: 37 ÷ 68 = 0.544118 (54.4118%)

Key Values:
- Simplified Fraction: 37/68
- Mixed Number Form: 37/68
- Decimal Value: 0.544118

Step-by-Step Solution: 2/8 + 5/17

Step 1

Find the Least Common Denominator (LCD)

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

LCD(8, 17) = 136

Step 2

Convert to Equivalent Fractions with Common Denominator 136

Multiply the numerator and denominator of 2/8 by 17, and multiply the numerator and denominator of 5/17 by 8 so both fractions share the common base 136.

2 × 17/8 × 17 = 34/136 and 5 × 8/17 × 8 = 40/136

Step 3

Add the Numerators

Now add the numerators (34 + 40 = 74) and keep the common denominator 136 unchanged.

34 + 40/136 = 74/136

Step 4

Simplify the Fraction to Lowest Terms

Find the Greatest Common Divisor (GCD) of 74 and 136, which is 2. Divide both the numerator and denominator by 2.

74 ÷ 2/136 ÷ 2 = 37/68

Step 5

Decimal & Percentage Representation

Dividing the numerator 37 by denominator 68 produces a repeating decimal (approximately 0.544118, or 54.4118%).

37 ÷ 68 = 0.544118 (54.4118%)
