Exact Answer

==================================================
Problem: What is 2/29 plus 9/22?
Formula / Expression: 2/29 + 9/22
Final Answer: 305/638
==================================================

Step-by-Step Solution:

Step 1: Find the Least Common Denominator (LCD)
The denominators 29 and 22 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 29 × 22 = 638.
Working: LCD(29, 22) = 638

Step 2: Convert to Equivalent Fractions with Common Denominator 638
Multiply the numerator and denominator of 2/29 by 22, and multiply the numerator and denominator of 9/22 by 29 so both fractions share the common base 638.
Working: 2 × 22/29 × 22 = 44/638 and 9 × 29/22 × 29 = 261/638

Step 3: Add the Numerators
Now add the numerators (44 + 261 = 305) and keep the common denominator 638 unchanged.
Working: 44 + 261/638 = 305/638

Step 4: Check if the Fraction Can Be Simplified
The Greatest Common Divisor (GCD) of 305 and 638 is 1, confirming that 305/638 cannot be reduced further—it is already in its simplest irreducible form.
Working: 305/638

Step 5: Decimal & Percentage Representation
Dividing the numerator 305 by denominator 638 produces a repeating decimal (approximately 0.478056, or 47.8056%).
Working: 305 ÷ 638 = 0.478056 (47.8056%)

Key Values:
- Simplified Fraction: 305/638
- Mixed Number Form: 305/638
- Decimal Value: 0.478056

Step-by-Step Solution: 2/29 + 9/22

Step 1

Find the Least Common Denominator (LCD)

The denominators 29 and 22 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 29 × 22 = 638.

LCD(29, 22) = 638

Step 2

Convert to Equivalent Fractions with Common Denominator 638

Multiply the numerator and denominator of 2/29 by 22, and multiply the numerator and denominator of 9/22 by 29 so both fractions share the common base 638.

2 × 22/29 × 22 = 44/638 and 9 × 29/22 × 29 = 261/638

Step 3

Add the Numerators

Now add the numerators (44 + 261 = 305) and keep the common denominator 638 unchanged.

44 + 261/638 = 305/638

Step 4

Check if the Fraction Can Be Simplified

The Greatest Common Divisor (GCD) of 305 and 638 is 1, confirming that 305/638 cannot be reduced further—it is already in its simplest irreducible form.
