What is 4/26 plus 2/7? (Answer: 40/91)

Exact Answer

==================================================
Problem: What is 4/26 plus 2/7?
Formula / Expression: 4/26 + 2/7
Final Answer: 40/91
==================================================

Step-by-Step Solution:

Step 1: Find the Least Common Denominator (LCD)
The denominators 26 and 7 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 26 × 7 = 182.
Working: LCD(26, 7) = 182

Step 2: Convert to Equivalent Fractions with Common Denominator 182
Multiply the numerator and denominator of 4/26 by 7, and multiply the numerator and denominator of 2/7 by 26 so both fractions share the common base 182.
Working: 4 × 7/26 × 7 = 28/182 and 2 × 26/7 × 26 = 52/182

Step 3: Add the Numerators
Now add the numerators (28 + 52 = 80) and keep the common denominator 182 unchanged.
Working: 28 + 52/182 = 80/182

Step 4: Simplify the Fraction to Lowest Terms
Find the Greatest Common Divisor (GCD) of 80 and 182, which is 2. Divide both the numerator and denominator by 2.
Working: 80 ÷ 2/182 ÷ 2 = 40/91

Step 5: Decimal & Percentage Representation
Dividing the numerator 40 by denominator 91 produces a repeating decimal (approximately 0.43956, or 43.956%).
Working: 40 ÷ 91 = 0.43956 (43.956%)

Key Values:
- Simplified Fraction: 40/91
- Mixed Number Form: 40/91
- Decimal Value: 0.43956
- Percentage: 43.956%

The denominators 26 and 7 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 26 × 7 = 182.

LCD(26, 7) = 182

Step 2

Convert to Equivalent Fractions with Common Denominator 182

Multiply the numerator and denominator of 4/26 by 7, and multiply the numerator and denominator of 2/7 by 26 so both fractions share the common base 182.

4 × 7/26 × 7 = 28/182 and 2 × 26/7 × 26 = 52/182

Step 3

Add the Numerators

Now add the numerators (28 + 52 = 80) and keep the common denominator 182 unchanged.

28 + 52/182 = 80/182

Step 4

Simplify the Fraction to Lowest Terms

Find the Greatest Common Divisor (GCD) of 80 and 182, which is 2. Divide both the numerator and denominator by 2.

80 ÷ 2/182 ÷ 2 = 40/91

Step 5
