What is 9/62 plus 3/13? (Answer: 303/806)

Exact Answer

==================================================
Problem: What is 9/62 plus 3/13?
Formula / Expression: 9/62 + 3/13
Final Answer: 303/806
==================================================

Step-by-Step Solution:

Step 1: Find the Least Common Denominator (LCD)
The denominators 62 and 13 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 62 × 13 = 806.
Working: LCD(62, 13) = 806

Step 2: Convert to Equivalent Fractions with Common Denominator 806
Multiply the numerator and denominator of 9/62 by 13, and multiply the numerator and denominator of 3/13 by 62 so both fractions share the common base 806.
Working: 9 × 13/62 × 13 = 117/806 and 3 × 62/13 × 62 = 186/806

Step 3: Add the Numerators
Now add the numerators (117 + 186 = 303) and keep the common denominator 806 unchanged.
Working: 117 + 186/806 = 303/806

Step 4: Check if the Fraction Can Be Simplified
The Greatest Common Divisor (GCD) of 303 and 806 is 1, confirming that 303/806 cannot be reduced further—it is already in its simplest irreducible form.
Working: 303/806

Step 5: Decimal & Percentage Representation
Dividing the numerator 303 by denominator 806 produces a repeating decimal (approximately 0.375931, or 37.5931%).
Working: 303 ÷ 806 = 0.375931 (37.5931%)

Key Values:
- Simplified Fraction: 303/806
- Mixed Number Form: 303/806
- Decimal Value: 0.375931

Step-by-Step Solution: 9/62 + 3/13

Step 1

Find the Least Common Denominator (LCD)

The denominators 62 and 13 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 62 × 13 = 806.

LCD(62, 13) = 806

Step 2

Convert to Equivalent Fractions with Common Denominator 806

Multiply the numerator and denominator of 9/62 by 13, and multiply the numerator and denominator of 3/13 by 62 so both fractions share the common base 806.

9 × 13/62 × 13 = 117/806 and 3 × 62/13 × 62 = 186/806

Step 3

Add the Numerators

Now add the numerators (117 + 186 = 303) and keep the common denominator 806 unchanged.

117 + 186/806 = 303/806

Step 4

Check if the Fraction Can Be Simplified

The Greatest Common Divisor (GCD) of 303 and 806 is 1, confirming that 303/806 cannot be reduced further—it is already in its simplest irreducible form.
