What is 4/17 plus 2/4? (Answer: 25/34)

Exact Answer

==================================================
Problem: What is 4/17 plus 2/4?
Formula / Expression: 4/17 + 2/4
Final Answer: 25/34
==================================================

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 4/17 by 4, and multiply the numerator and denominator of 2/4 by 17 so both fractions share the common base 68.
Working: 4 × 4/17 × 4 = 16/68 and 2 × 17/4 × 17 = 34/68

Step 3: Add the Numerators
Now add the numerators (16 + 34 = 50) and keep the common denominator 68 unchanged.
Working: 16 + 34/68 = 50/68

Step 4: Simplify the Fraction to Lowest Terms
Find the Greatest Common Divisor (GCD) of 50 and 68, which is 2. Divide both the numerator and denominator by 2.
Working: 50 ÷ 2/68 ÷ 2 = 25/34

Step 5: Decimal & Percentage Representation
Dividing the numerator 25 by denominator 34 produces a repeating decimal (approximately 0.735294, or 73.5294%).
Working: 25 ÷ 34 = 0.735294 (73.5294%)

Key Values:
- Simplified Fraction: 25/34
- Mixed Number Form: 25/34
- Decimal Value: 0.735294
- Percentage: 73.5294%

Step-by-Step Solution: 4/17 + 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 4/17 by 4, and multiply the numerator and denominator of 2/4 by 17 so both fractions share the common base 68.

4 × 4/17 × 4 = 16/68 and 2 × 17/4 × 17 = 34/68

Step 3

Add the Numerators

Now add the numerators (16 + 34 = 50) and keep the common denominator 68 unchanged.

16 + 34/68 = 50/68

Step 4

Simplify the Fraction to Lowest Terms

Find the Greatest Common Divisor (GCD) of 50 and 68, which is 2. Divide both the numerator and denominator by 2.

50 ÷ 2/68 ÷ 2 = 25/34

Step 5

Decimal & Percentage Representation

Dividing the numerator 25 by denominator 34 produces a repeating decimal (approximately 0.735294, or 73.5294%).
