Exact Answer

==================================================
Problem: What is 14/41 plus 10/21?
Formula / Expression: 14/41 + 10/21
Final Answer: 704/861
==================================================

Step-by-Step Solution:

Step 1: Find the Least Common Denominator (LCD)
The denominators 41 and 21 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 41 × 21 = 861.
Working: LCD(41, 21) = 861

Step 2: Convert to Equivalent Fractions with Common Denominator 861
Multiply the numerator and denominator of 14/41 by 21, and multiply the numerator and denominator of 10/21 by 41 so both fractions share the common base 861.
Working: 14 × 21/41 × 21 = 294/861 and 10 × 41/21 × 41 = 410/861

Step 3: Add the Numerators
Now add the numerators (294 + 410 = 704) and keep the common denominator 861 unchanged.
Working: 294 + 410/861 = 704/861

Step 4: Check if the Fraction Can Be Simplified
The Greatest Common Divisor (GCD) of 704 and 861 is 1, confirming that 704/861 cannot be reduced further—it is already in its simplest irreducible form.
Working: 704/861

Step 5: Decimal & Percentage Representation
Dividing the numerator 704 by denominator 861 produces a repeating decimal (approximately 0.817654, or 81.7654%).
Working: 704 ÷ 861 = 0.817654 (81.7654%)

Key Values:
- Simplified Fraction: 704/861
- Mixed Number Form: 704/861
- Decimal Value: 0.817654
- Percentage: 81.7654%

Step-by-Step Solution: 14/41 + 10/21

Step 1

Find the Least Common Denominator (LCD)

The denominators 41 and 21 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 41 × 21 = 861.

LCD(41, 21) = 861

Step 2

Convert to Equivalent Fractions with Common Denominator 861

Multiply the numerator and denominator of 14/41 by 21, and multiply the numerator and denominator of 10/21 by 41 so both fractions share the common base 861.

14 × 21/41 × 21 = 294/861 and 10 × 41/21 × 41 = 410/861

Step 3

Add the Numerators

Now add the numerators (294 + 410 = 704) and keep the common denominator 861 unchanged.

294 + 410/861 = 704/861

Step 4

Check if the Fraction Can Be Simplified

The Greatest Common Divisor (GCD) of 704 and 861 is 1, confirming that 704/861 cannot be reduced further—it is already in its simplest irreducible form.

704/861

Step 5
