Exact Answer

==================================================
Problem: What is 2/25 plus 4/9?
Formula / Expression: 2/25 + 4/9
Final Answer: 118/225
==================================================

Step-by-Step Solution:

Step 1: Find the Least Common Denominator (LCD)
The denominators 25 and 9 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 25 × 9 = 225.
Working: LCD(25, 9) = 225

Step 2: Convert to Equivalent Fractions with Common Denominator 225
Multiply the numerator and denominator of 2/25 by 9, and multiply the numerator and denominator of 4/9 by 25 so both fractions share the common base 225.
Working: 2 × 9/25 × 9 = 18/225 and 4 × 25/9 × 25 = 100/225

Step 3: Add the Numerators
Now add the numerators (18 + 100 = 118) and keep the common denominator 225 unchanged.
Working: 18 + 100/225 = 118/225

Step 4: Check if the Fraction Can Be Simplified
The Greatest Common Divisor (GCD) of 118 and 225 is 1, confirming that 118/225 cannot be reduced further—it is already in its simplest irreducible form.
Working: 118/225

Step 5: Decimal & Percentage Representation
Dividing the numerator 118 by denominator 225 produces a repeating decimal (approximately 0.524444, or 52.4444%).
Working: 118 ÷ 225 = 0.524444 (52.4444%)

Key Values:
- Simplified Fraction: 118/225
- Mixed Number Form: 118/225
- Decimal Value: 0.524444
- Percentage: 52.4444%

Step-by-Step Solution: 2/25 + 4/9

Step 1

Find the Least Common Denominator (LCD)

The denominators 25 and 9 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 25 × 9 = 225.

LCD(25, 9) = 225

Step 2

Convert to Equivalent Fractions with Common Denominator 225

Multiply the numerator and denominator of 2/25 by 9, and multiply the numerator and denominator of 4/9 by 25 so both fractions share the common base 225.

2 × 9/25 × 9 = 18/225 and 4 × 25/9 × 25 = 100/225

Step 3

Add the Numerators

Now add the numerators (18 + 100 = 118) and keep the common denominator 225 unchanged.

18 + 100/225 = 118/225

Step 4

Check if the Fraction Can Be Simplified

The Greatest Common Divisor (GCD) of 118 and 225 is 1, confirming that 118/225 cannot be reduced further—it is already in its simplest irreducible form.
