Exact Answer

==================================================
Problem: What is 4/38 plus 2/9?
Formula / Expression: 4/38 + 2/9
Final Answer: 56/171
==================================================

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 4/38 by 9, and multiply the numerator and denominator of 2/9 by 38 so both fractions share the common base 342.
Working: 4 × 9/38 × 9 = 36/342 and 2 × 38/9 × 38 = 76/342

Step 3: Add the Numerators
Now add the numerators (36 + 76 = 112) and keep the common denominator 342 unchanged.
Working: 36 + 76/342 = 112/342

Step 4: Simplify the Fraction to Lowest Terms
Find the Greatest Common Divisor (GCD) of 112 and 342, which is 2. Divide both the numerator and denominator by 2.
Working: 112 ÷ 2/342 ÷ 2 = 56/171

Step 5: Decimal & Percentage Representation
Dividing the numerator 56 by denominator 171 produces a repeating decimal (approximately 0.327485, or 32.7485%).
Working: 56 ÷ 171 = 0.327485 (32.7485%)

Key Values:
- Simplified Fraction: 56/171
- Mixed Number Form: 56/171
- Decimal Value: 0.327485
- Percentage: 32.7485%

Step-by-Step Solution: 4/38 + 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 4/38 by 9, and multiply the numerator and denominator of 2/9 by 38 so both fractions share the common base 342.

4 × 9/38 × 9 = 36/342 and 2 × 38/9 × 38 = 76/342

Step 3

Add the Numerators

Now add the numerators (36 + 76 = 112) and keep the common denominator 342 unchanged.

36 + 76/342 = 112/342

Step 4

Simplify the Fraction to Lowest Terms

Find the Greatest Common Divisor (GCD) of 112 and 342, which is 2. Divide both the numerator and denominator by 2.

112 ÷ 2/342 ÷ 2 = 56/171

Step 5

Decimal & Percentage Representation

Dividing the numerator 56 by denominator 171 produces a repeating decimal (approximately 0.327485, or 32.7485%).

56 ÷ 171 = 0.327485 (32.7485%)
