Exact Answer

==================================================
Problem: What is 2/22 plus 4/9?
Formula / Expression: 2/22 + 4/9
Final Answer: 53/99
==================================================

Step-by-Step Solution:

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

Step 2: Convert to Equivalent Fractions with Common Denominator 198
Multiply the numerator and denominator of 2/22 by 9, and multiply the numerator and denominator of 4/9 by 22 so both fractions share the common base 198.
Working: 2 × 9/22 × 9 = 18/198 and 4 × 22/9 × 22 = 88/198

Step 3: Add the Numerators
Now add the numerators (18 + 88 = 106) and keep the common denominator 198 unchanged.
Working: 18 + 88/198 = 106/198

Step 4: Simplify the Fraction to Lowest Terms
Find the Greatest Common Divisor (GCD) of 106 and 198, which is 2. Divide both the numerator and denominator by 2.
Working: 106 ÷ 2/198 ÷ 2 = 53/99

Step 5: Decimal & Percentage Representation
Dividing the numerator 53 by denominator 99 produces a repeating decimal (approximately 0.535354, or 53.5354%).
Working: 53 ÷ 99 = 0.535354 (53.5354%)

Key Values:
- Simplified Fraction: 53/99
- Mixed Number Form: 53/99
- Decimal Value: 0.535354

Step-by-Step Solution: 2/22 + 4/9

Step 1

Find the Least Common Denominator (LCD)

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

LCD(22, 9) = 198

Step 2

Convert to Equivalent Fractions with Common Denominator 198

Multiply the numerator and denominator of 2/22 by 9, and multiply the numerator and denominator of 4/9 by 22 so both fractions share the common base 198.

2 × 9/22 × 9 = 18/198 and 4 × 22/9 × 22 = 88/198

Step 3

Add the Numerators

Now add the numerators (18 + 88 = 106) and keep the common denominator 198 unchanged.

18 + 88/198 = 106/198

Step 4

Simplify the Fraction to Lowest Terms

Find the Greatest Common Divisor (GCD) of 106 and 198, which is 2. Divide both the numerator and denominator by 2.

106 ÷ 2/198 ÷ 2 = 53/99

Step 5

Decimal & Percentage Representation

Dividing the numerator 53 by denominator 99 produces a repeating decimal (approximately 0.535354, or 53.5354%).

53 ÷ 99 = 0.535354 (53.5354%)
