What is 5/13 plus 2/4? (Answer: 23/26)

Exact Answer

==================================================
Problem: What is 5/13 plus 2/4?
Formula / Expression: 5/13 + 2/4
Final Answer: 23/26
==================================================

Step-by-Step Solution:

Step 1: Find the Least Common Denominator (LCD)
The denominators 13 and 4 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 13 × 4 = 52.
Working: LCD(13, 4) = 52

Step 2: Convert to Equivalent Fractions with Common Denominator 52
Multiply the numerator and denominator of 5/13 by 4, and multiply the numerator and denominator of 2/4 by 13 so both fractions share the common base 52.
Working: 5 × 4/13 × 4 = 20/52 and 2 × 13/4 × 13 = 26/52

Step 3: Add the Numerators
Now add the numerators (20 + 26 = 46) and keep the common denominator 52 unchanged.
Working: 20 + 26/52 = 46/52

Step 4: Simplify the Fraction to Lowest Terms
Find the Greatest Common Divisor (GCD) of 46 and 52, which is 2. Divide both the numerator and denominator by 2.
Working: 46 ÷ 2/52 ÷ 2 = 23/26

Step 5: Decimal & Percentage Representation
Dividing the numerator 23 by denominator 26 produces a repeating decimal (approximately 0.884615, or 88.4615%).
Working: 23 ÷ 26 = 0.884615 (88.4615%)

Key Values:
- Simplified Fraction: 23/26
- Mixed Number Form: 23/26
- Decimal Value: 0.884615
- Percentage: 88.4615%

Step-by-Step Solution: 5/13 + 2/4

Step 1

Find the Least Common Denominator (LCD)

The denominators 13 and 4 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 13 × 4 = 52.

LCD(13, 4) = 52

Step 2

Convert to Equivalent Fractions with Common Denominator 52

Multiply the numerator and denominator of 5/13 by 4, and multiply the numerator and denominator of 2/4 by 13 so both fractions share the common base 52.

5 × 4/13 × 4 = 20/52 and 2 × 13/4 × 13 = 26/52

Step 3

Add the Numerators

Now add the numerators (20 + 26 = 46) and keep the common denominator 52 unchanged.

20 + 26/52 = 46/52

Step 4

Simplify the Fraction to Lowest Terms

Find the Greatest Common Divisor (GCD) of 46 and 52, which is 2. Divide both the numerator and denominator by 2.

46 ÷ 2/52 ÷ 2 = 23/26

Step 5

Decimal & Percentage Representation

Dividing the numerator 23 by denominator 26 produces a repeating decimal (approximately 0.884615, or 88.4615%).

23 ÷ 26 = 0.884615 (88.4615%)
