Exact Answer

==================================================
Problem: What is 10/34 plus 8/13?
Formula / Expression: 10/34 + 8/13
Final Answer: 201/221
==================================================

Step-by-Step Solution:

Step 1: Find the Least Common Denominator (LCD)
The denominators 34 and 13 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 34 × 13 = 442.
Working: LCD(34, 13) = 442

Step 2: Convert to Equivalent Fractions with Common Denominator 442
Multiply the numerator and denominator of 10/34 by 13, and multiply the numerator and denominator of 8/13 by 34 so both fractions share the common base 442.
Working: 10 × 13/34 × 13 = 130/442 and 8 × 34/13 × 34 = 272/442

Step 3: Add the Numerators
Now add the numerators (130 + 272 = 402) and keep the common denominator 442 unchanged.
Working: 130 + 272/442 = 402/442

Step 4: Simplify the Fraction to Lowest Terms
Find the Greatest Common Divisor (GCD) of 402 and 442, which is 2. Divide both the numerator and denominator by 2.
Working: 402 ÷ 2/442 ÷ 2 = 201/221

Step 5: Decimal & Percentage Representation
Dividing the numerator 201 by denominator 221 produces a repeating decimal (approximately 0.909502, or 90.9502%).
Working: 201 ÷ 221 = 0.909502 (90.9502%)

Key Values:
- Simplified Fraction: 201/221
- Mixed Number Form: 201/221
- Decimal Value: 0.909502
- Percentage: 90.9502%

Step-by-Step Solution: 10/34 + 8/13

Step 1

Find the Least Common Denominator (LCD)

The denominators 34 and 13 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 34 × 13 = 442.

LCD(34, 13) = 442

Step 2

Convert to Equivalent Fractions with Common Denominator 442

Multiply the numerator and denominator of 10/34 by 13, and multiply the numerator and denominator of 8/13 by 34 so both fractions share the common base 442.

10 × 13/34 × 13 = 130/442 and 8 × 34/13 × 34 = 272/442

Step 3

Add the Numerators

Now add the numerators (130 + 272 = 402) and keep the common denominator 442 unchanged.

130 + 272/442 = 402/442

Step 4

Simplify the Fraction to Lowest Terms

Find the Greatest Common Divisor (GCD) of 402 and 442, which is 2. Divide both the numerator and denominator by 2.

402 ÷ 2/442 ÷ 2 = 201/221

Step 5

Decimal & Percentage Representation

Dividing the numerator 201 by denominator 221 produces a repeating decimal (approximately 0.909502, or 90.9502%).

201 ÷ 221 = 0.909502 (90.9502%)
