What is 9/34 plus 2/7? (Answer: 131/238)

Exact Answer

==================================================
Problem: What is 9/34 plus 2/7?
Formula / Expression: 9/34 + 2/7
Final Answer: 131/238
==================================================

Step-by-Step Solution:

Step 1: Find the Least Common Denominator (LCD)
The denominators 34 and 7 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 34 × 7 = 238.
Working: LCD(34, 7) = 238

Step 2: Convert to Equivalent Fractions with Common Denominator 238
Multiply the numerator and denominator of 9/34 by 7, and multiply the numerator and denominator of 2/7 by 34 so both fractions share the common base 238.
Working: 9 × 7/34 × 7 = 63/238 and 2 × 34/7 × 34 = 68/238

Step 3: Add the Numerators
Now add the numerators (63 + 68 = 131) and keep the common denominator 238 unchanged.
Working: 63 + 68/238 = 131/238

Step 4: Check if the Fraction Can Be Simplified
The Greatest Common Divisor (GCD) of 131 and 238 is 1, confirming that 131/238 cannot be reduced further—it is already in its simplest irreducible form.
Working: 131/238

Step 5: Decimal & Percentage Representation
Dividing the numerator 131 by denominator 238 produces a repeating decimal (approximately 0.55042, or 55.042%).
Working: 131 ÷ 238 = 0.55042 (55.042%)

Key Values:
- Simplified Fraction: 131/238
- Mixed Number Form: 131/238
- Decimal Value: 0.55042
- Percentage: 55.042%

The denominators 34 and 7 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 34 × 7 = 238.

LCD(34, 7) = 238

Step 2

Convert to Equivalent Fractions with Common Denominator 238

Multiply the numerator and denominator of 9/34 by 7, and multiply the numerator and denominator of 2/7 by 34 so both fractions share the common base 238.

9 × 7/34 × 7 = 63/238 and 2 × 34/7 × 34 = 68/238

Step 3

Add the Numerators

Now add the numerators (63 + 68 = 131) and keep the common denominator 238 unchanged.

63 + 68/238 = 131/238

Step 4

Check if the Fraction Can Be Simplified

The Greatest Common Divisor (GCD) of 131 and 238 is 1, confirming that 131/238 cannot be reduced further—it is already in its simplest irreducible form.

131/238

Step 5
