What is 8/29 plus 2/7? (Answer: 114/203)

Exact Answer

==================================================
Problem: What is 8/29 plus 2/7?
Formula / Expression: 8/29 + 2/7
Final Answer: 114/203
==================================================

Step-by-Step Solution:

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

Step 2: Convert to Equivalent Fractions with Common Denominator 203
Multiply the numerator and denominator of 8/29 by 7, and multiply the numerator and denominator of 2/7 by 29 so both fractions share the common base 203.
Working: 8 × 7/29 × 7 = 56/203 and 2 × 29/7 × 29 = 58/203

Step 3: Add the Numerators
Now add the numerators (56 + 58 = 114) and keep the common denominator 203 unchanged.
Working: 56 + 58/203 = 114/203

Step 4: Check if the Fraction Can Be Simplified
The Greatest Common Divisor (GCD) of 114 and 203 is 1, confirming that 114/203 cannot be reduced further—it is already in its simplest irreducible form.
Working: 114/203

Step 5: Decimal & Percentage Representation
Dividing the numerator 114 by denominator 203 produces a repeating decimal (approximately 0.561576, or 56.1576%).
Working: 114 ÷ 203 = 0.561576 (56.1576%)

Key Values:
- Simplified Fraction: 114/203
- Mixed Number Form: 114/203
- Decimal Value: 0.561576
- Percentage: 56.1576%

Step-by-Step Solution: 8/29 + 2/7

Step 1

Find the Least Common Denominator (LCD)

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

LCD(29, 7) = 203

Step 2

Convert to Equivalent Fractions with Common Denominator 203

Multiply the numerator and denominator of 8/29 by 7, and multiply the numerator and denominator of 2/7 by 29 so both fractions share the common base 203.

8 × 7/29 × 7 = 56/203 and 2 × 29/7 × 29 = 58/203

Step 3

Add the Numerators

Now add the numerators (56 + 58 = 114) and keep the common denominator 203 unchanged.

56 + 58/203 = 114/203

Step 4

Check if the Fraction Can Be Simplified

The Greatest Common Divisor (GCD) of 114 and 203 is 1, confirming that 114/203 cannot be reduced further—it is already in its simplest irreducible form.
