Exact Answer

==================================================
Problem: What is 9/58 plus 4/13?
Formula / Expression: 9/58 + 4/13
Final Answer: 349/754
==================================================

Step-by-Step Solution:

Step 1: Find the Least Common Denominator (LCD)
The denominators 58 and 13 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 58 × 13 = 754.
Working: LCD(58, 13) = 754

Step 2: Convert to Equivalent Fractions with Common Denominator 754
Multiply the numerator and denominator of 9/58 by 13, and multiply the numerator and denominator of 4/13 by 58 so both fractions share the common base 754.
Working: 9 × 13/58 × 13 = 117/754 and 4 × 58/13 × 58 = 232/754

Step 3: Add the Numerators
Now add the numerators (117 + 232 = 349) and keep the common denominator 754 unchanged.
Working: 117 + 232/754 = 349/754

Step 4: Check if the Fraction Can Be Simplified
The Greatest Common Divisor (GCD) of 349 and 754 is 1, confirming that 349/754 cannot be reduced further—it is already in its simplest irreducible form.
Working: 349/754

Step 5: Decimal & Percentage Representation
Dividing the numerator 349 by denominator 754 produces a repeating decimal (approximately 0.462865, or 46.2865%).
Working: 349 ÷ 754 = 0.462865 (46.2865%)

Key Values:
- Simplified Fraction: 349/754
- Mixed Number Form: 349/754
- Decimal Value: 0.462865

Step-by-Step Solution: 9/58 + 4/13

Step 1

Find the Least Common Denominator (LCD)

The denominators 58 and 13 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 58 × 13 = 754.

LCD(58, 13) = 754

Step 2

Convert to Equivalent Fractions with Common Denominator 754

Multiply the numerator and denominator of 9/58 by 13, and multiply the numerator and denominator of 4/13 by 58 so both fractions share the common base 754.

9 × 13/58 × 13 = 117/754 and 4 × 58/13 × 58 = 232/754

Step 3

Add the Numerators

Now add the numerators (117 + 232 = 349) and keep the common denominator 754 unchanged.

117 + 232/754 = 349/754

Step 4

Check if the Fraction Can Be Simplified
