Exact Answer

==================================================
Problem: What is 2/38 plus 2/9?
Formula / Expression: 2/38 + 2/9
Final Answer: 47/171
==================================================

Step-by-Step Solution:

Step 1: Find the Least Common Denominator (LCD)
The denominators 38 and 9 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 38 × 9 = 342.
Working: LCD(38, 9) = 342

Step 2: Convert to Equivalent Fractions with Common Denominator 342
Multiply the numerator and denominator of 2/38 by 9, and multiply the numerator and denominator of 2/9 by 38 so both fractions share the common base 342.
Working: 2 × 9/38 × 9 = 18/342 and 2 × 38/9 × 38 = 76/342

Step 3: Add the Numerators
Now add the numerators (18 + 76 = 94) and keep the common denominator 342 unchanged.
Working: 18 + 76/342 = 94/342

Step 4: Simplify the Fraction to Lowest Terms
Find the Greatest Common Divisor (GCD) of 94 and 342, which is 2. Divide both the numerator and denominator by 2.
Working: 94 ÷ 2/342 ÷ 2 = 47/171

Step 5: Decimal & Percentage Representation
Dividing the numerator 47 by denominator 171 produces a repeating decimal (approximately 0.274854, or 27.4854%).
Working: 47 ÷ 171 = 0.274854 (27.4854%)

Key Values:
- Simplified Fraction: 47/171
- Mixed Number Form: 47/171
- Decimal Value: 0.274854

Step-by-Step Solution: 2/38 + 2/9

Step 1

Find the Least Common Denominator (LCD)

The denominators 38 and 9 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 38 × 9 = 342.

LCD(38, 9) = 342

Step 2

Convert to Equivalent Fractions with Common Denominator 342

Multiply the numerator and denominator of 2/38 by 9, and multiply the numerator and denominator of 2/9 by 38 so both fractions share the common base 342.

2 × 9/38 × 9 = 18/342 and 2 × 38/9 × 38 = 76/342

Step 3

Add the Numerators

Now add the numerators (18 + 76 = 94) and keep the common denominator 342 unchanged.

18 + 76/342 = 94/342

Step 4

Simplify the Fraction to Lowest Terms

Find the Greatest Common Divisor (GCD) of 94 and 342, which is 2. Divide both the numerator and denominator by 2.

94 ÷ 2/342 ÷ 2 = 47/171

Step 5

Decimal & Percentage Representation

Dividing the numerator 47 by denominator 171 produces a repeating decimal (approximately 0.274854, or 27.4854%).
