Exact Answer

==================================================
Problem: What is 9/64 plus 2/13?
Formula / Expression: 9/64 + 2/13
Final Answer: 245/832
==================================================

Step-by-Step Solution:

Step 1: Find the Least Common Denominator (LCD)
The denominators 64 and 13 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 64 × 13 = 832.
Working: LCD(64, 13) = 832

Step 2: Convert to Equivalent Fractions with Common Denominator 832
Multiply the numerator and denominator of 9/64 by 13, and multiply the numerator and denominator of 2/13 by 64 so both fractions share the common base 832.
Working: 9 × 13/64 × 13 = 117/832 and 2 × 64/13 × 64 = 128/832

Step 3: Add the Numerators
Now add the numerators (117 + 128 = 245) and keep the common denominator 832 unchanged.
Working: 117 + 128/832 = 245/832

Step 4: Check if the Fraction Can Be Simplified
The Greatest Common Divisor (GCD) of 245 and 832 is 1, confirming that 245/832 cannot be reduced further—it is already in its simplest irreducible form.
Working: 245/832

Step 5: Decimal & Percentage Representation
Dividing the numerator 245 by denominator 832 produces a repeating decimal (approximately 0.294471, or 29.4471%).
Working: 245 ÷ 832 = 0.294471 (29.4471%)

Key Values:
- Simplified Fraction: 245/832
- Mixed Number Form: 245/832
- Decimal Value: 0.294471

Step-by-Step Solution: 9/64 + 2/13

Step 1

Find the Least Common Denominator (LCD)

The denominators 64 and 13 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 64 × 13 = 832.

LCD(64, 13) = 832

Step 2

Convert to Equivalent Fractions with Common Denominator 832

Multiply the numerator and denominator of 9/64 by 13, and multiply the numerator and denominator of 2/13 by 64 so both fractions share the common base 832.

9 × 13/64 × 13 = 117/832 and 2 × 64/13 × 64 = 128/832

Step 3

Add the Numerators

Now add the numerators (117 + 128 = 245) and keep the common denominator 832 unchanged.

117 + 128/832 = 245/832

Step 4

Check if the Fraction Can Be Simplified

The Greatest Common Divisor (GCD) of 245 and 832 is 1, confirming that 245/832 cannot be reduced further—it is already in its simplest irreducible form.

245/832
