What is 4/26 plus 3/13? (Answer: 5/13)

Exact Answer

==================================================
Problem: What is 4/26 plus 3/13?
Formula / Expression: 4/26 + 3/13
Final Answer: 5/13
==================================================

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 3/13 by 2 so both fractions share the common base 26.
Working: 4 × 1/26 × 1 = 4/26 and 3 × 2/13 × 2 = 6/26

Step 3: Add the Numerators
Now add the numerators (4 + 6 = 10) and keep the common denominator 26 unchanged.
Working: 4 + 6/26 = 10/26

Step 4: Simplify the Fraction to Lowest Terms
Find the Greatest Common Divisor (GCD) of 10 and 26, which is 2. Divide both the numerator and denominator by 2.
Working: 10 ÷ 2/26 ÷ 2 = 5/13

Step 5: Decimal & Percentage Representation
Dividing the numerator 5 by denominator 13 produces a repeating decimal (approximately 0.384615, or 38.4615%).
Working: 5 ÷ 13 = 0.384615 (38.4615%)

Key Values:
- Simplified Fraction: 5/13
- Mixed Number Form: 5/13
- Decimal Value: 0.384615

Step-by-Step Solution: 4/26 + 3/13

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.

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 3/13 by 2 so both fractions share the common base 26.

4 × 1/26 × 1 = 4/26 and 3 × 2/13 × 2 = 6/26

Step 3

Add the Numerators

Now add the numerators (4 + 6 = 10) and keep the common denominator 26 unchanged.

4 + 6/26 = 10/26

Step 4

Simplify the Fraction to Lowest Terms

Find the Greatest Common Divisor (GCD) of 10 and 26, which is 2. Divide both the numerator and denominator by 2.

10 ÷ 2/26 ÷ 2 = 5/13

Step 5

Decimal & Percentage Representation

Dividing the numerator 5 by denominator 13 produces a repeating decimal (approximately 0.384615, or 38.4615%).

5 ÷ 13 = 0.384615 (38.4615%)
