Exact Answer

==================================================
Problem: What is 8/54 plus 2/13?
Formula / Expression: 8/54 + 2/13
Final Answer: 106/351
==================================================

Step-by-Step Solution:

Step 1: Find the Least Common Denominator (LCD)
The denominators 54 and 13 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 54 × 13 = 702.
Working: LCD(54, 13) = 702

Step 2: Convert to Equivalent Fractions with Common Denominator 702
Multiply the numerator and denominator of 8/54 by 13, and multiply the numerator and denominator of 2/13 by 54 so both fractions share the common base 702.
Working: 8 × 13/54 × 13 = 104/702 and 2 × 54/13 × 54 = 108/702

Step 3: Add the Numerators
Now add the numerators (104 + 108 = 212) and keep the common denominator 702 unchanged.
Working: 104 + 108/702 = 212/702

Step 4: Simplify the Fraction to Lowest Terms
Find the Greatest Common Divisor (GCD) of 212 and 702, which is 2. Divide both the numerator and denominator by 2.
Working: 212 ÷ 2/702 ÷ 2 = 106/351

Step 5: Decimal & Percentage Representation
Dividing the numerator 106 by denominator 351 produces a repeating decimal (approximately 0.301994, or 30.1994%).
Working: 106 ÷ 351 = 0.301994 (30.1994%)

Key Values:
- Simplified Fraction: 106/351
- Mixed Number Form: 106/351
- Decimal Value: 0.301994
- Percentage: 30.1994%

Step-by-Step Solution: 8/54 + 2/13

Step 1

Find the Least Common Denominator (LCD)

The denominators 54 and 13 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 54 × 13 = 702.

LCD(54, 13) = 702

Step 2

Convert to Equivalent Fractions with Common Denominator 702

Multiply the numerator and denominator of 8/54 by 13, and multiply the numerator and denominator of 2/13 by 54 so both fractions share the common base 702.

8 × 13/54 × 13 = 104/702 and 2 × 54/13 × 54 = 108/702

Step 3

Add the Numerators

Now add the numerators (104 + 108 = 212) and keep the common denominator 702 unchanged.

104 + 108/702 = 212/702

Step 4

Simplify the Fraction to Lowest Terms

Find the Greatest Common Divisor (GCD) of 212 and 702, which is 2. Divide both the numerator and denominator by 2.

212 ÷ 2/702 ÷ 2 = 106/351

Step 5

Decimal & Percentage Representation

Dividing the numerator 106 by denominator 351 produces a repeating decimal (approximately 0.301994, or 30.1994%).

106 ÷ 351 = 0.301994 (30.1994%)
