Exact Answer

==================================================
Problem: What is 2/7 plus 9/25?
Formula / Expression: 2/7 + 9/25
Final Answer: 113/175
==================================================

Step-by-Step Solution:

Step 1: Find the Least Common Denominator (LCD)
The denominators 7 and 25 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 7 × 25 = 175.
Working: LCD(7, 25) = 175

Step 2: Convert to Equivalent Fractions with Common Denominator 175
Multiply the numerator and denominator of 2/7 by 25, and multiply the numerator and denominator of 9/25 by 7 so both fractions share the common base 175.
Working: 2 × 25/7 × 25 = 50/175 and 9 × 7/25 × 7 = 63/175

Step 3: Add the Numerators
Now add the numerators (50 + 63 = 113) and keep the common denominator 175 unchanged.
Working: 50 + 63/175 = 113/175

Step 4: Check if the Fraction Can Be Simplified
The Greatest Common Divisor (GCD) of 113 and 175 is 1, confirming that 113/175 cannot be reduced further—it is already in its simplest irreducible form.
Working: 113/175

Step 5: Decimal & Percentage Representation
Dividing the numerator 113 by denominator 175 produces a repeating decimal (approximately 0.645714, or 64.5714%).
Working: 113 ÷ 175 = 0.645714 (64.5714%)

Key Values:
- Simplified Fraction: 113/175
- Mixed Number Form: 113/175
- Decimal Value: 0.645714

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

Step 1

Find the Least Common Denominator (LCD)

The denominators 7 and 25 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 7 × 25 = 175.

LCD(7, 25) = 175

Step 2

Convert to Equivalent Fractions with Common Denominator 175

Multiply the numerator and denominator of 2/7 by 25, and multiply the numerator and denominator of 9/25 by 7 so both fractions share the common base 175.

2 × 25/7 × 25 = 50/175 and 9 × 7/25 × 7 = 63/175

Step 3

Add the Numerators

Now add the numerators (50 + 63 = 113) and keep the common denominator 175 unchanged.

50 + 63/175 = 113/175

Step 4

Check if the Fraction Can Be Simplified

The Greatest Common Divisor (GCD) of 113 and 175 is 1, confirming that 113/175 cannot be reduced further—it is already in its simplest irreducible form.
