Exact Answer

==================================================
Problem: What is 4/26 plus 7/13?
Formula / Expression: 4/26 + 7/13
Final Answer: 9/13
==================================================

Step-by-Step Solution:

Step 1: Find the Least Common Denominator (LCD)
Notice that 26 is an exact multiple of 13 (13 × 2 = 26). The Least Common Denominator (LCD) is simply 26, meaning we only need to scale one fraction.
Working: LCD(26, 13) = 26

Step 2: Convert to Equivalent Fractions with Common Denominator 26
Multiply the numerator and denominator of 4/26 by 1, and multiply the numerator and denominator of 7/13 by 2 so both fractions share the common base 26.
Working: 4 × 1/26 × 1 = 4/26 and 7 × 2/13 × 2 = 14/26

Step 3: Add the Numerators
Now add the numerators (4 + 14 = 18) and keep the common denominator 26 unchanged.
Working: 4 + 14/26 = 18/26

Step 4: Simplify the Fraction to Lowest Terms
Find the Greatest Common Divisor (GCD) of 18 and 26, which is 2. Divide both the numerator and denominator by 2.
Working: 18 ÷ 2/26 ÷ 2 = 9/13

Step 5: Decimal & Percentage Representation
Dividing the numerator 9 by denominator 13 produces a repeating decimal (approximately 0.692308, or 69.2308%).
Working: 9 ÷ 13 = 0.692308 (69.2308%)

Key Values:
- Simplified Fraction: 9/13
- Mixed Number Form: 9/13
- Decimal Value: 0.692308
- Percentage: 69.2308%

Find the Least Common Denominator (LCD)

Notice that 26 is an exact multiple of 13 (13 × 2 = 26). The Least Common Denominator (LCD) is simply 26, meaning we only need to scale one fraction.

LCD(26, 13) = 26

Step 2

Convert to Equivalent Fractions with Common Denominator 26

Multiply the numerator and denominator of 4/26 by 1, and multiply the numerator and denominator of 7/13 by 2 so both fractions share the common base 26.

4 × 1/26 × 1 = 4/26 and 7 × 2/13 × 2 = 14/26

Step 3

Add the Numerators

Now add the numerators (4 + 14 = 18) and keep the common denominator 26 unchanged.

4 + 14/26 = 18/26

Step 4

Simplify the Fraction to Lowest Terms
