Exact Answer

==================================================
Problem: What is 2/22 plus 3/9?
Formula / Expression: 2/22 + 3/9
Final Answer: 14/33
==================================================

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 3/9 by 22 so both fractions share the common base 198.
Working: 2 × 9/22 × 9 = 18/198 and 3 × 22/9 × 22 = 66/198

Step 3: Add the Numerators
Now add the numerators (18 + 66 = 84) and keep the common denominator 198 unchanged.
Working: 18 + 66/198 = 84/198

Step 4: Simplify the Fraction to Lowest Terms
Find the Greatest Common Divisor (GCD) of 84 and 198, which is 6. Divide both the numerator and denominator by 6.
Working: 84 ÷ 6/198 ÷ 6 = 14/33

Step 5: Decimal & Percentage Representation
Dividing the numerator 14 by denominator 33 produces a repeating decimal (approximately 0.424242, or 42.4242%).
Working: 14 ÷ 33 = 0.424242 (42.4242%)

Key Values:
- Simplified Fraction: 14/33
- Mixed Number Form: 14/33
- Decimal Value: 0.424242
- Percentage: 42.4242%

Step-by-Step Solution: 2/22 + 3/9

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 3/9 by 22 so both fractions share the common base 198.

2 × 9/22 × 9 = 18/198 and 3 × 22/9 × 22 = 66/198

Step 3

Add the Numerators

Now add the numerators (18 + 66 = 84) and keep the common denominator 198 unchanged.

18 + 66/198 = 84/198

Step 4

Simplify the Fraction to Lowest Terms

Find the Greatest Common Divisor (GCD) of 84 and 198, which is 6. Divide both the numerator and denominator by 6.

84 ÷ 6/198 ÷ 6 = 14/33

Step 5

Decimal & Percentage Representation

Dividing the numerator 14 by denominator 33 produces a repeating decimal (approximately 0.424242, or 42.4242%).

14 ÷ 33 = 0.424242 (42.4242%)
