What is 2/7 plus 9/29? (Answer: 121/203)

Exact Answer

==================================================
Problem: What is 2/7 plus 9/29?
Formula / Expression: 2/7 + 9/29
Final Answer: 121/203
==================================================

Step-by-Step Solution:

Step 1: Find the Least Common Denominator (LCD)
The denominators 7 and 29 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 7 × 29 = 203.
Working: LCD(7, 29) = 203

Step 2: Convert to Equivalent Fractions with Common Denominator 203
Multiply the numerator and denominator of 2/7 by 29, and multiply the numerator and denominator of 9/29 by 7 so both fractions share the common base 203.
Working: 2 × 29/7 × 29 = 58/203 and 9 × 7/29 × 7 = 63/203

Step 3: Add the Numerators
Now add the numerators (58 + 63 = 121) and keep the common denominator 203 unchanged.
Working: 58 + 63/203 = 121/203

Step 4: Check if the Fraction Can Be Simplified
The Greatest Common Divisor (GCD) of 121 and 203 is 1, confirming that 121/203 cannot be reduced further—it is already in its simplest irreducible form.
Working: 121/203

Step 5: Decimal & Percentage Representation
Dividing the numerator 121 by denominator 203 produces a repeating decimal (approximately 0.596059, or 59.6059%).
Working: 121 ÷ 203 = 0.596059 (59.6059%)

Key Values:
- Simplified Fraction: 121/203
- Mixed Number Form: 121/203
- Decimal Value: 0.596059
- Percentage: 59.6059%

Step-by-Step Solution: 2/7 + 9/29

Step 1

Find the Least Common Denominator (LCD)

The denominators 7 and 29 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 7 × 29 = 203.

LCD(7, 29) = 203

Step 2

Convert to Equivalent Fractions with Common Denominator 203

Multiply the numerator and denominator of 2/7 by 29, and multiply the numerator and denominator of 9/29 by 7 so both fractions share the common base 203.

2 × 29/7 × 29 = 58/203 and 9 × 7/29 × 7 = 63/203

Step 3

Add the Numerators

Now add the numerators (58 + 63 = 121) and keep the common denominator 203 unchanged.

58 + 63/203 = 121/203

Step 4

Check if the Fraction Can Be Simplified

The Greatest Common Divisor (GCD) of 121 and 203 is 1, confirming that 121/203 cannot be reduced further—it is already in its simplest irreducible form.

121/203

Step 5

Decimal & Percentage Representation
