Exact Answer

==================================================
Problem: What is 2/9 plus 8/22?
Formula / Expression: 2/9 + 8/22
Final Answer: 58/99
==================================================

Step-by-Step Solution:

Step 1: Find the Least Common Denominator (LCD)
The denominators 9 and 22 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 9 × 22 = 198.
Working: LCD(9, 22) = 198

Step 2: Convert to Equivalent Fractions with Common Denominator 198
Multiply the numerator and denominator of 2/9 by 22, and multiply the numerator and denominator of 8/22 by 9 so both fractions share the common base 198.
Working: 2 × 22/9 × 22 = 44/198 and 8 × 9/22 × 9 = 72/198

Step 3: Add the Numerators
Now add the numerators (44 + 72 = 116) and keep the common denominator 198 unchanged.
Working: 44 + 72/198 = 116/198

Step 4: Simplify the Fraction to Lowest Terms
Find the Greatest Common Divisor (GCD) of 116 and 198, which is 2. Divide both the numerator and denominator by 2.
Working: 116 ÷ 2/198 ÷ 2 = 58/99

Step 5: Decimal & Percentage Representation
Dividing the numerator 58 by denominator 99 produces a repeating decimal (approximately 0.585859, or 58.5859%).
Working: 58 ÷ 99 = 0.585859 (58.5859%)

Key Values:
- Simplified Fraction: 58/99
- Mixed Number Form: 58/99
- Decimal Value: 0.585859

Step-by-Step Solution: 2/9 + 8/22

Step 1

Find the Least Common Denominator (LCD)

The denominators 9 and 22 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 9 × 22 = 198.

LCD(9, 22) = 198

Step 2

Convert to Equivalent Fractions with Common Denominator 198

Multiply the numerator and denominator of 2/9 by 22, and multiply the numerator and denominator of 8/22 by 9 so both fractions share the common base 198.

2 × 22/9 × 22 = 44/198 and 8 × 9/22 × 9 = 72/198

Step 3

Add the Numerators

Now add the numerators (44 + 72 = 116) and keep the common denominator 198 unchanged.

44 + 72/198 = 116/198

Step 4

Simplify the Fraction to Lowest Terms

Find the Greatest Common Divisor (GCD) of 116 and 198, which is 2. Divide both the numerator and denominator by 2.

116 ÷ 2/198 ÷ 2 = 58/99

Step 5

Decimal & Percentage Representation

Dividing the numerator 58 by denominator 99 produces a repeating decimal (approximately 0.585859, or 58.5859%).

58 ÷ 99 = 0.585859 (58.5859%)
