What is 5/11 plus 2/4? (Answer: 21/22)

Exact Answer

==================================================
Problem: What is 5/11 plus 2/4?
Formula / Expression: 5/11 + 2/4
Final Answer: 21/22
==================================================

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 5/11 by 4, and multiply the numerator and denominator of 2/4 by 11 so both fractions share the common base 44.
Working: 5 × 4/11 × 4 = 20/44 and 2 × 11/4 × 11 = 22/44

Step 3: Add the Numerators
Now add the numerators (20 + 22 = 42) and keep the common denominator 44 unchanged.
Working: 20 + 22/44 = 42/44

Step 4: Simplify the Fraction to Lowest Terms
Find the Greatest Common Divisor (GCD) of 42 and 44, which is 2. Divide both the numerator and denominator by 2.
Working: 42 ÷ 2/44 ÷ 2 = 21/22

Step 5: Decimal & Percentage Representation
Dividing the numerator 21 by denominator 22 produces a repeating decimal (approximately 0.954545, or 95.4545%).
Working: 21 ÷ 22 = 0.954545 (95.4545%)

Key Values:
- Simplified Fraction: 21/22
- Mixed Number Form: 21/22
- Decimal Value: 0.954545
- Percentage: 95.4545%

Step-by-Step Solution: 5/11 + 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 5/11 by 4, and multiply the numerator and denominator of 2/4 by 11 so both fractions share the common base 44.

5 × 4/11 × 4 = 20/44 and 2 × 11/4 × 11 = 22/44

Step 3

Add the Numerators

Now add the numerators (20 + 22 = 42) and keep the common denominator 44 unchanged.

20 + 22/44 = 42/44

Step 4

Simplify the Fraction to Lowest Terms

Find the Greatest Common Divisor (GCD) of 42 and 44, which is 2. Divide both the numerator and denominator by 2.

42 ÷ 2/44 ÷ 2 = 21/22

Step 5

Decimal & Percentage Representation

Dividing the numerator 21 by denominator 22 produces a repeating decimal (approximately 0.954545, or 95.4545%).

21 ÷ 22 = 0.954545 (95.4545%)
