What is 1/17 plus 2/4? (Answer: 19/34)

Exact Answer

==================================================
Problem: What is 1/17 plus 2/4?
Formula / Expression: 1/17 + 2/4
Final Answer: 19/34
==================================================

Step-by-Step Solution:

Step 1: Find the Least Common Denominator (LCD)
The denominators 17 and 4 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 17 × 4 = 68.
Working: LCD(17, 4) = 68

Step 2: Convert to Equivalent Fractions with Common Denominator 68
Multiply the numerator and denominator of 1/17 by 4, and multiply the numerator and denominator of 2/4 by 17 so both fractions share the common base 68.
Working: 1 × 4/17 × 4 = 4/68 and 2 × 17/4 × 17 = 34/68

Step 3: Add the Numerators
Now add the numerators (4 + 34 = 38) and keep the common denominator 68 unchanged.
Working: 4 + 34/68 = 38/68

Step 4: Simplify the Fraction to Lowest Terms
Find the Greatest Common Divisor (GCD) of 38 and 68, which is 2. Divide both the numerator and denominator by 2.
Working: 38 ÷ 2/68 ÷ 2 = 19/34

Step 5: Decimal & Percentage Representation
Dividing the numerator 19 by denominator 34 produces a repeating decimal (approximately 0.558824, or 55.8824%).
Working: 19 ÷ 34 = 0.558824 (55.8824%)

Key Values:
- Simplified Fraction: 19/34
- Mixed Number Form: 19/34
- Decimal Value: 0.558824
- Percentage: 55.8824%

Step-by-Step Solution: 1/17 + 2/4

Step 1

Find the Least Common Denominator (LCD)

The denominators 17 and 4 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 17 × 4 = 68.

LCD(17, 4) = 68

Step 2

Convert to Equivalent Fractions with Common Denominator 68

Multiply the numerator and denominator of 1/17 by 4, and multiply the numerator and denominator of 2/4 by 17 so both fractions share the common base 68.

1 × 4/17 × 4 = 4/68 and 2 × 17/4 × 17 = 34/68

Step 3

Add the Numerators

Now add the numerators (4 + 34 = 38) and keep the common denominator 68 unchanged.

4 + 34/68 = 38/68

Step 4

Simplify the Fraction to Lowest Terms

Find the Greatest Common Divisor (GCD) of 38 and 68, which is 2. Divide both the numerator and denominator by 2.

38 ÷ 2/68 ÷ 2 = 19/34

Step 5

Decimal & Percentage Representation

Dividing the numerator 19 by denominator 34 produces a repeating decimal (approximately 0.558824, or 55.8824%).

19 ÷ 34 = 0.558824 (55.8824%)
