Exact Answer

==================================================
Problem: What is 2/9 plus 7/25?
Formula / Expression: 2/9 + 7/25
Final Answer: 113/225
==================================================

Step-by-Step Solution:

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

Step 2: Convert to Equivalent Fractions with Common Denominator 225
Multiply the numerator and denominator of 2/9 by 25, and multiply the numerator and denominator of 7/25 by 9 so both fractions share the common base 225.
Working: 2 × 25/9 × 25 = 50/225 and 7 × 9/25 × 9 = 63/225

Step 3: Add the Numerators
Now add the numerators (50 + 63 = 113) and keep the common denominator 225 unchanged.
Working: 50 + 63/225 = 113/225

Step 4: Check if the Fraction Can Be Simplified
The Greatest Common Divisor (GCD) of 113 and 225 is 1, confirming that 113/225 cannot be reduced further—it is already in its simplest irreducible form.
Working: 113/225

Step 5: Decimal & Percentage Representation
Dividing the numerator 113 by denominator 225 produces a repeating decimal (approximately 0.502222, or 50.2222%).
Working: 113 ÷ 225 = 0.502222 (50.2222%)

Key Values:
- Simplified Fraction: 113/225
- Mixed Number Form: 113/225
- Decimal Value: 0.502222
- Percentage: 50.2222%

Step-by-Step Solution: 2/9 + 7/25

Step 1

Find the Least Common Denominator (LCD)

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

LCD(9, 25) = 225

Step 2

Convert to Equivalent Fractions with Common Denominator 225

Multiply the numerator and denominator of 2/9 by 25, and multiply the numerator and denominator of 7/25 by 9 so both fractions share the common base 225.

2 × 25/9 × 25 = 50/225 and 7 × 9/25 × 9 = 63/225

Step 3

Add the Numerators

Now add the numerators (50 + 63 = 113) and keep the common denominator 225 unchanged.

50 + 63/225 = 113/225

Step 4

Check if the Fraction Can Be Simplified

The Greatest Common Divisor (GCD) of 113 and 225 is 1, confirming that 113/225 cannot be reduced further—it is already in its simplest irreducible form.

113/225

Step 5

Decimal & Percentage Representation
