Exact Answer

==================================================
Problem: What is 9/68 plus 2/13?
Formula / Expression: 9/68 + 2/13
Final Answer: 253/884
==================================================

Step-by-Step Solution:

Step 1: Find the Least Common Denominator (LCD)
The denominators 68 and 13 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 68 × 13 = 884.
Working: LCD(68, 13) = 884

Step 2: Convert to Equivalent Fractions with Common Denominator 884
Multiply the numerator and denominator of 9/68 by 13, and multiply the numerator and denominator of 2/13 by 68 so both fractions share the common base 884.
Working: 9 × 13/68 × 13 = 117/884 and 2 × 68/13 × 68 = 136/884

Step 3: Add the Numerators
Now add the numerators (117 + 136 = 253) and keep the common denominator 884 unchanged.
Working: 117 + 136/884 = 253/884

Step 4: Check if the Fraction Can Be Simplified
The Greatest Common Divisor (GCD) of 253 and 884 is 1, confirming that 253/884 cannot be reduced further—it is already in its simplest irreducible form.
Working: 253/884

Step 5: Decimal & Percentage Representation
Dividing the numerator 253 by denominator 884 produces a repeating decimal (approximately 0.286199, or 28.6199%).
Working: 253 ÷ 884 = 0.286199 (28.6199%)

Key Values:
- Simplified Fraction: 253/884
- Mixed Number Form: 253/884

Step-by-Step Solution: 9/68 + 2/13

Step 1

Find the Least Common Denominator (LCD)

The denominators 68 and 13 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 68 × 13 = 884.

LCD(68, 13) = 884

Step 2

Convert to Equivalent Fractions with Common Denominator 884

Multiply the numerator and denominator of 9/68 by 13, and multiply the numerator and denominator of 2/13 by 68 so both fractions share the common base 884.

9 × 13/68 × 13 = 117/884 and 2 × 68/13 × 68 = 136/884

Step 3

Add the Numerators

Now add the numerators (117 + 136 = 253) and keep the common denominator 884 unchanged.

117 + 136/884 = 253/884

Step 4

Check if the Fraction Can Be Simplified
