Exact Answer

==================================================
Problem: What is 2/28 plus 2/13?
Formula / Expression: 2/28 + 2/13
Final Answer: 41/182
==================================================

Step-by-Step Solution:

Step 1: Find the Least Common Denominator (LCD)
The denominators 28 and 13 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 28 × 13 = 364.
Working: LCD(28, 13) = 364

Step 2: Convert to Equivalent Fractions with Common Denominator 364
Multiply the numerator and denominator of 2/28 by 13, and multiply the numerator and denominator of 2/13 by 28 so both fractions share the common base 364.
Working: 2 × 13/28 × 13 = 26/364 and 2 × 28/13 × 28 = 56/364

Step 3: Add the Numerators
Now add the numerators (26 + 56 = 82) and keep the common denominator 364 unchanged.
Working: 26 + 56/364 = 82/364

Step 4: Simplify the Fraction to Lowest Terms
Find the Greatest Common Divisor (GCD) of 82 and 364, which is 2. Divide both the numerator and denominator by 2.
Working: 82 ÷ 2/364 ÷ 2 = 41/182

Step 5: Decimal & Percentage Representation
Dividing the numerator 41 by denominator 182 produces a repeating decimal (approximately 0.225275, or 22.5275%).
Working: 41 ÷ 182 = 0.225275 (22.5275%)

Key Values:
- Simplified Fraction: 41/182
- Mixed Number Form: 41/182
- Decimal Value: 0.225275
- Percentage: 22.5275%

Step-by-Step Solution: 2/28 + 2/13

Step 1

Find the Least Common Denominator (LCD)

The denominators 28 and 13 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 28 × 13 = 364.

LCD(28, 13) = 364

Step 2

Convert to Equivalent Fractions with Common Denominator 364

Multiply the numerator and denominator of 2/28 by 13, and multiply the numerator and denominator of 2/13 by 28 so both fractions share the common base 364.

2 × 13/28 × 13 = 26/364 and 2 × 28/13 × 28 = 56/364

Step 3

Add the Numerators

Now add the numerators (26 + 56 = 82) and keep the common denominator 364 unchanged.

26 + 56/364 = 82/364

Step 4

Simplify the Fraction to Lowest Terms

Find the Greatest Common Divisor (GCD) of 82 and 364, which is 2. Divide both the numerator and denominator by 2.

82 ÷ 2/364 ÷ 2 = 41/182

Step 5

Decimal & Percentage Representation

Dividing the numerator 41 by denominator 182 produces a repeating decimal (approximately 0.225275, or 22.5275%).

41 ÷ 182 = 0.225275 (22.5275%)
