What is 4/26 plus 2/8? (Answer: 21/52)

Exact Answer

==================================================
Problem: What is 4/26 plus 2/8?
Formula / Expression: 4/26 + 2/8
Final Answer: 21/52
==================================================

Step-by-Step Solution:

Step 1: Find the Least Common Denominator (LCD)
The denominators 26 and 8 share a common factor (GCD = 2). Finding their Least Common Multiple gives an LCD of 104 (which is smaller than their product 26 × 8 = 208, keeping the calculation simpler).
Working: LCD(26, 8) = 104

Step 2: Convert to Equivalent Fractions with Common Denominator 104
Multiply the numerator and denominator of 4/26 by 4, and multiply the numerator and denominator of 2/8 by 13 so both fractions share the common base 104.
Working: 4 × 4/26 × 4 = 16/104 and 2 × 13/8 × 13 = 26/104

Step 3: Add the Numerators
Now add the numerators (16 + 26 = 42) and keep the common denominator 104 unchanged.
Working: 16 + 26/104 = 42/104

Step 4: Simplify the Fraction to Lowest Terms
Find the Greatest Common Divisor (GCD) of 42 and 104, which is 2. Divide both the numerator and denominator by 2.
Working: 42 ÷ 2/104 ÷ 2 = 21/52

Step 5: Decimal & Percentage Representation
Dividing the numerator 21 by denominator 52 produces a repeating decimal (approximately 0.403846, or 40.3846%).
Working: 21 ÷ 52 = 0.403846 (40.3846%)

Key Values:
- Simplified Fraction: 21/52
- Mixed Number Form: 21/52
- Decimal Value: 0.403846
- Percentage: 40.3846%

Step-by-Step Solution: 4/26 + 2/8

Step 1

Find the Least Common Denominator (LCD)

The denominators 26 and 8 share a common factor (GCD = 2). Finding their Least Common Multiple gives an LCD of 104 (which is smaller than their product 26 × 8 = 208, keeping the calculation simpler).

LCD(26, 8) = 104

Step 2

Convert to Equivalent Fractions with Common Denominator 104

Multiply the numerator and denominator of 4/26 by 4, and multiply the numerator and denominator of 2/8 by 13 so both fractions share the common base 104.

4 × 4/26 × 4 = 16/104 and 2 × 13/8 × 13 = 26/104

Step 3

Add the Numerators

Now add the numerators (16 + 26 = 42) and keep the common denominator 104 unchanged.

16 + 26/104 = 42/104

Step 4

Simplify the Fraction to Lowest Terms

Find the Greatest Common Divisor (GCD) of 42 and 104, which is 2. Divide both the numerator and denominator by 2.

42 ÷ 2/104 ÷ 2 = 21/52

Step 5

Decimal & Percentage Representation

Dividing the numerator 21 by denominator 52 produces a repeating decimal (approximately 0.403846, or 40.3846%).

21 ÷ 52 = 0.403846 (40.3846%)
