Exact Answer

==================================================
Problem: What is 4/27 plus 2/4?
Formula / Expression: 4/27 + 2/4
Final Answer: 35/54
==================================================

Step-by-Step Solution:

Step 1: Find the Least Common Denominator (LCD)
The denominators 27 and 4 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 27 × 4 = 108.
Working: LCD(27, 4) = 108

Step 2: Convert to Equivalent Fractions with Common Denominator 108
Multiply the numerator and denominator of 4/27 by 4, and multiply the numerator and denominator of 2/4 by 27 so both fractions share the common base 108.
Working: 4 × 4/27 × 4 = 16/108 and 2 × 27/4 × 27 = 54/108

Step 3: Add the Numerators
Now add the numerators (16 + 54 = 70) and keep the common denominator 108 unchanged.
Working: 16 + 54/108 = 70/108

Step 4: Simplify the Fraction to Lowest Terms
Find the Greatest Common Divisor (GCD) of 70 and 108, which is 2. Divide both the numerator and denominator by 2.
Working: 70 ÷ 2/108 ÷ 2 = 35/54

Step 5: Decimal & Percentage Representation
Dividing the numerator 35 by denominator 54 produces a repeating decimal (approximately 0.648148, or 64.8148%).
Working: 35 ÷ 54 = 0.648148 (64.8148%)

Key Values:
- Simplified Fraction: 35/54
- Mixed Number Form: 35/54
- Decimal Value: 0.648148
- Percentage: 64.8148%

Step-by-Step Solution: 4/27 + 2/4

Step 1

Find the Least Common Denominator (LCD)

The denominators 27 and 4 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 27 × 4 = 108.

LCD(27, 4) = 108

Step 2

Convert to Equivalent Fractions with Common Denominator 108

Multiply the numerator and denominator of 4/27 by 4, and multiply the numerator and denominator of 2/4 by 27 so both fractions share the common base 108.

4 × 4/27 × 4 = 16/108 and 2 × 27/4 × 27 = 54/108

Step 3

Add the Numerators

Now add the numerators (16 + 54 = 70) and keep the common denominator 108 unchanged.

16 + 54/108 = 70/108

Step 4

Simplify the Fraction to Lowest Terms

Find the Greatest Common Divisor (GCD) of 70 and 108, which is 2. Divide both the numerator and denominator by 2.

70 ÷ 2/108 ÷ 2 = 35/54

Step 5

Decimal & Percentage Representation

Dividing the numerator 35 by denominator 54 produces a repeating decimal (approximately 0.648148, or 64.8148%).

35 ÷ 54 = 0.648148 (64.8148%)
