What is 3/11 plus 2/4? (Answer: 17/22)

Exact Answer

==================================================
Problem: What is 3/11 plus 2/4?
Formula / Expression: 3/11 + 2/4
Final Answer: 17/22
==================================================

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 3/11 by 4, and multiply the numerator and denominator of 2/4 by 11 so both fractions share the common base 44.
Working: 3 × 4/11 × 4 = 12/44 and 2 × 11/4 × 11 = 22/44

Step 3: Add the Numerators
Now add the numerators (12 + 22 = 34) and keep the common denominator 44 unchanged.
Working: 12 + 22/44 = 34/44

Step 4: Simplify the Fraction to Lowest Terms
Find the Greatest Common Divisor (GCD) of 34 and 44, which is 2. Divide both the numerator and denominator by 2.
Working: 34 ÷ 2/44 ÷ 2 = 17/22

Step 5: Decimal & Percentage Representation
Dividing the numerator 17 by denominator 22 produces a repeating decimal (approximately 0.772727, or 77.2727%).
Working: 17 ÷ 22 = 0.772727 (77.2727%)

Key Values:
- Simplified Fraction: 17/22
- Mixed Number Form: 17/22
- Decimal Value: 0.772727
- Percentage: 77.2727%

Step-by-Step Solution: 3/11 + 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 3/11 by 4, and multiply the numerator and denominator of 2/4 by 11 so both fractions share the common base 44.

3 × 4/11 × 4 = 12/44 and 2 × 11/4 × 11 = 22/44

Step 3

Add the Numerators

Now add the numerators (12 + 22 = 34) and keep the common denominator 44 unchanged.

12 + 22/44 = 34/44

Step 4

Simplify the Fraction to Lowest Terms

Find the Greatest Common Divisor (GCD) of 34 and 44, which is 2. Divide both the numerator and denominator by 2.

34 ÷ 2/44 ÷ 2 = 17/22

Step 5

Decimal & Percentage Representation

Dividing the numerator 17 by denominator 22 produces a repeating decimal (approximately 0.772727, or 77.2727%).

17 ÷ 22 = 0.772727 (77.2727%)
