What is 4/11 plus 2/4? (Answer: 19/22)

Exact Answer

==================================================
Problem: What is 4/11 plus 2/4?
Formula / Expression: 4/11 + 2/4
Final Answer: 19/22
==================================================

Step-by-Step Solution:

Step 1: Find the Least Common Denominator (LCD)
The denominators 11 and 4 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 11 × 4 = 44.
Working: LCD(11, 4) = 44

Step 2: Convert to Equivalent Fractions with Common Denominator 44
Multiply the numerator and denominator of 4/11 by 4, and multiply the numerator and denominator of 2/4 by 11 so both fractions share the common base 44.
Working: 4 × 4/11 × 4 = 16/44 and 2 × 11/4 × 11 = 22/44

Step 3: Add the Numerators
Now add the numerators (16 + 22 = 38) and keep the common denominator 44 unchanged.
Working: 16 + 22/44 = 38/44

Step 4: Simplify the Fraction to Lowest Terms
Find the Greatest Common Divisor (GCD) of 38 and 44, which is 2. Divide both the numerator and denominator by 2.
Working: 38 ÷ 2/44 ÷ 2 = 19/22

Step 5: Decimal & Percentage Representation
Dividing the numerator 19 by denominator 22 produces a repeating decimal (approximately 0.863636, or 86.3636%).
Working: 19 ÷ 22 = 0.863636 (86.3636%)

Key Values:
- Simplified Fraction: 19/22
- Mixed Number Form: 19/22
- Decimal Value: 0.863636
- Percentage: 86.3636%

Step-by-Step Solution: 4/11 + 2/4

Step 1

Find the Least Common Denominator (LCD)

The denominators 11 and 4 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 11 × 4 = 44.

LCD(11, 4) = 44

Step 2

Convert to Equivalent Fractions with Common Denominator 44

Multiply the numerator and denominator of 4/11 by 4, and multiply the numerator and denominator of 2/4 by 11 so both fractions share the common base 44.

4 × 4/11 × 4 = 16/44 and 2 × 11/4 × 11 = 22/44

Step 3

Add the Numerators

Now add the numerators (16 + 22 = 38) and keep the common denominator 44 unchanged.

16 + 22/44 = 38/44

Step 4

Simplify the Fraction to Lowest Terms

Find the Greatest Common Divisor (GCD) of 38 and 44, which is 2. Divide both the numerator and denominator by 2.

38 ÷ 2/44 ÷ 2 = 19/22

Step 5

Decimal & Percentage Representation

Dividing the numerator 19 by denominator 22 produces a repeating decimal (approximately 0.863636, or 86.3636%).

19 ÷ 22 = 0.863636 (86.3636%)
