Exact Answer

==================================================
Problem: What is 10/29 plus 7/13?
Formula / Expression: 10/29 + 7/13
Final Answer: 333/377
==================================================

Step-by-Step Solution:

Step 1: Find the Least Common Denominator (LCD)
The denominators 29 and 13 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 29 × 13 = 377.
Working: LCD(29, 13) = 377

Step 2: Convert to Equivalent Fractions with Common Denominator 377
Multiply the numerator and denominator of 10/29 by 13, and multiply the numerator and denominator of 7/13 by 29 so both fractions share the common base 377.
Working: 10 × 13/29 × 13 = 130/377 and 7 × 29/13 × 29 = 203/377

Step 3: Add the Numerators
Now add the numerators (130 + 203 = 333) and keep the common denominator 377 unchanged.
Working: 130 + 203/377 = 333/377

Step 4: Check if the Fraction Can Be Simplified
The Greatest Common Divisor (GCD) of 333 and 377 is 1, confirming that 333/377 cannot be reduced further—it is already in its simplest irreducible form.
Working: 333/377

Step 5: Decimal & Percentage Representation
Dividing the numerator 333 by denominator 377 produces a repeating decimal (approximately 0.883289, or 88.3289%).
Working: 333 ÷ 377 = 0.883289 (88.3289%)

Key Values:
- Simplified Fraction: 333/377
- Mixed Number Form: 333/377
- Decimal Value: 0.883289

Step-by-Step Solution: 10/29 + 7/13

Step 1

Find the Least Common Denominator (LCD)

The denominators 29 and 13 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 29 × 13 = 377.

LCD(29, 13) = 377

Step 2

Convert to Equivalent Fractions with Common Denominator 377

Multiply the numerator and denominator of 10/29 by 13, and multiply the numerator and denominator of 7/13 by 29 so both fractions share the common base 377.

10 × 13/29 × 13 = 130/377 and 7 × 29/13 × 29 = 203/377

Step 3

Add the Numerators

Now add the numerators (130 + 203 = 333) and keep the common denominator 377 unchanged.

130 + 203/377 = 333/377

Step 4

Check if the Fraction Can Be Simplified
