Exact Answer

==================================================
Problem: What is 2/38 plus 11/13?
Formula / Expression: 2/38 + 11/13
Final Answer: 222/247
==================================================

Step-by-Step Solution:

Step 1: Find the Least Common Denominator (LCD)
The denominators 38 and 13 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 38 × 13 = 494.
Working: LCD(38, 13) = 494

Step 2: Convert to Equivalent Fractions with Common Denominator 494
Multiply the numerator and denominator of 2/38 by 13, and multiply the numerator and denominator of 11/13 by 38 so both fractions share the common base 494.
Working: 2 × 13/38 × 13 = 26/494 and 11 × 38/13 × 38 = 418/494

Step 3: Add the Numerators
Now add the numerators (26 + 418 = 444) and keep the common denominator 494 unchanged.
Working: 26 + 418/494 = 444/494

Step 4: Simplify the Fraction to Lowest Terms
Find the Greatest Common Divisor (GCD) of 444 and 494, which is 2. Divide both the numerator and denominator by 2.
Working: 444 ÷ 2/494 ÷ 2 = 222/247

Step 5: Decimal & Percentage Representation
Dividing the numerator 222 by denominator 247 produces a repeating decimal (approximately 0.898785, or 89.8785%).
Working: 222 ÷ 247 = 0.898785 (89.8785%)

Key Values:
- Simplified Fraction: 222/247
- Mixed Number Form: 222/247
- Decimal Value: 0.898785
- Percentage: 89.8785%

Step-by-Step Solution: 2/38 + 11/13

Step 1

Find the Least Common Denominator (LCD)

The denominators 38 and 13 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 38 × 13 = 494.

LCD(38, 13) = 494

Step 2

Convert to Equivalent Fractions with Common Denominator 494

Multiply the numerator and denominator of 2/38 by 13, and multiply the numerator and denominator of 11/13 by 38 so both fractions share the common base 494.

2 × 13/38 × 13 = 26/494 and 11 × 38/13 × 38 = 418/494

Step 3

Add the Numerators

Now add the numerators (26 + 418 = 444) and keep the common denominator 494 unchanged.

26 + 418/494 = 444/494

Step 4

Simplify the Fraction to Lowest Terms

Find the Greatest Common Divisor (GCD) of 444 and 494, which is 2. Divide both the numerator and denominator by 2.

444 ÷ 2/494 ÷ 2 = 222/247

Step 5

Decimal & Percentage Representation

Dividing the numerator 222 by denominator 247 produces a repeating decimal (approximately 0.898785, or 89.8785%).

222 ÷ 247 = 0.898785 (89.8785%)
