Exact Answer

==================================================
Problem: What is 6/57 plus 2/13?
Formula / Expression: 6/57 + 2/13
Final Answer: 64/247
==================================================

Step-by-Step Solution:

Step 1: Find the Least Common Denominator (LCD)
The denominators 57 and 13 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 57 × 13 = 741.
Working: LCD(57, 13) = 741

Step 2: Convert to Equivalent Fractions with Common Denominator 741
Multiply the numerator and denominator of 6/57 by 13, and multiply the numerator and denominator of 2/13 by 57 so both fractions share the common base 741.
Working: 6 × 13/57 × 13 = 78/741 and 2 × 57/13 × 57 = 114/741

Step 3: Add the Numerators
Now add the numerators (78 + 114 = 192) and keep the common denominator 741 unchanged.
Working: 78 + 114/741 = 192/741

Step 4: Simplify the Fraction to Lowest Terms
Find the Greatest Common Divisor (GCD) of 192 and 741, which is 3. Divide both the numerator and denominator by 3.
Working: 192 ÷ 3/741 ÷ 3 = 64/247

Step 5: Decimal & Percentage Representation
Dividing the numerator 64 by denominator 247 produces a repeating decimal (approximately 0.259109, or 25.9109%).
Working: 64 ÷ 247 = 0.259109 (25.9109%)

Key Values:
- Simplified Fraction: 64/247
- Mixed Number Form: 64/247
- Decimal Value: 0.259109
- Percentage: 25.9109%

Step-by-Step Solution: 6/57 + 2/13

Step 1

Find the Least Common Denominator (LCD)

The denominators 57 and 13 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 57 × 13 = 741.

LCD(57, 13) = 741

Step 2

Convert to Equivalent Fractions with Common Denominator 741

Multiply the numerator and denominator of 6/57 by 13, and multiply the numerator and denominator of 2/13 by 57 so both fractions share the common base 741.

6 × 13/57 × 13 = 78/741 and 2 × 57/13 × 57 = 114/741

Step 3

Add the Numerators

Now add the numerators (78 + 114 = 192) and keep the common denominator 741 unchanged.

78 + 114/741 = 192/741

Step 4

Simplify the Fraction to Lowest Terms

Find the Greatest Common Divisor (GCD) of 192 and 741, which is 3. Divide both the numerator and denominator by 3.

192 ÷ 3/741 ÷ 3 = 64/247

Step 5

Decimal & Percentage Representation

Dividing the numerator 64 by denominator 247 produces a repeating decimal (approximately 0.259109, or 25.9109%).

64 ÷ 247 = 0.259109 (25.9109%)
