Exact Answer

==================================================
Problem: What is 2/34 plus 11/21?
Formula / Expression: 2/34 + 11/21
Final Answer: 208/357
==================================================

Step-by-Step Solution:

Step 1: Find the Least Common Denominator (LCD)
The denominators 34 and 21 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 34 × 21 = 714.
Working: LCD(34, 21) = 714

Step 2: Convert to Equivalent Fractions with Common Denominator 714
Multiply the numerator and denominator of 2/34 by 21, and multiply the numerator and denominator of 11/21 by 34 so both fractions share the common base 714.
Working: 2 × 21/34 × 21 = 42/714 and 11 × 34/21 × 34 = 374/714

Step 3: Add the Numerators
Now add the numerators (42 + 374 = 416) and keep the common denominator 714 unchanged.
Working: 42 + 374/714 = 416/714

Step 4: Simplify the Fraction to Lowest Terms
Find the Greatest Common Divisor (GCD) of 416 and 714, which is 2. Divide both the numerator and denominator by 2.
Working: 416 ÷ 2/714 ÷ 2 = 208/357

Step 5: Decimal & Percentage Representation
Dividing the numerator 208 by denominator 357 produces a repeating decimal (approximately 0.582633, or 58.2633%).
Working: 208 ÷ 357 = 0.582633 (58.2633%)

Key Values:
- Simplified Fraction: 208/357
- Mixed Number Form: 208/357
- Decimal Value: 0.582633
- Percentage: 58.2633%

Step-by-Step Solution: 2/34 + 11/21

Step 1

Find the Least Common Denominator (LCD)

The denominators 34 and 21 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 34 × 21 = 714.

LCD(34, 21) = 714

Step 2

Convert to Equivalent Fractions with Common Denominator 714

Multiply the numerator and denominator of 2/34 by 21, and multiply the numerator and denominator of 11/21 by 34 so both fractions share the common base 714.

2 × 21/34 × 21 = 42/714 and 11 × 34/21 × 34 = 374/714

Step 3

Add the Numerators

Now add the numerators (42 + 374 = 416) and keep the common denominator 714 unchanged.

42 + 374/714 = 416/714

Step 4

Simplify the Fraction to Lowest Terms

Find the Greatest Common Divisor (GCD) of 416 and 714, which is 2. Divide both the numerator and denominator by 2.

416 ÷ 2/714 ÷ 2 = 208/357

Step 5

Decimal & Percentage Representation

Dividing the numerator 208 by denominator 357 produces a repeating decimal (approximately 0.582633, or 58.2633%).

208 ÷ 357 = 0.582633 (58.2633%)
