Exact Answer

==================================================
Problem: What is 1/46 plus 10/21?
Formula / Expression: 1/46 + 10/21
Final Answer: 481/966
==================================================

Step-by-Step Solution:

Step 1: Find the Least Common Denominator (LCD)
The denominators 46 and 21 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 46 × 21 = 966.
Working: LCD(46, 21) = 966

Step 2: Convert to Equivalent Fractions with Common Denominator 966
Multiply the numerator and denominator of 1/46 by 21, and multiply the numerator and denominator of 10/21 by 46 so both fractions share the common base 966.
Working: 1 × 21/46 × 21 = 21/966 and 10 × 46/21 × 46 = 460/966

Step 3: Add the Numerators
Now add the numerators (21 + 460 = 481) and keep the common denominator 966 unchanged.
Working: 21 + 460/966 = 481/966

Step 4: Check if the Fraction Can Be Simplified
The Greatest Common Divisor (GCD) of 481 and 966 is 1, confirming that 481/966 cannot be reduced further—it is already in its simplest irreducible form.
Working: 481/966

Step 5: Decimal & Percentage Representation
Dividing the numerator 481 by denominator 966 produces a repeating decimal (approximately 0.49793, or 49.793%).
Working: 481 ÷ 966 = 0.49793 (49.793%)

Key Values:
- Simplified Fraction: 481/966
- Mixed Number Form: 481/966
- Decimal Value: 0.49793

Step-by-Step Solution: 1/46 + 10/21

Step 1

Find the Least Common Denominator (LCD)

The denominators 46 and 21 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 46 × 21 = 966.

LCD(46, 21) = 966

Step 2

Convert to Equivalent Fractions with Common Denominator 966

Multiply the numerator and denominator of 1/46 by 21, and multiply the numerator and denominator of 10/21 by 46 so both fractions share the common base 966.

1 × 21/46 × 21 = 21/966 and 10 × 46/21 × 46 = 460/966

Step 3

Add the Numerators

Now add the numerators (21 + 460 = 481) and keep the common denominator 966 unchanged.

21 + 460/966 = 481/966

Step 4

Check if the Fraction Can Be Simplified

The Greatest Common Divisor (GCD) of 481 and 966 is 1, confirming that 481/966 cannot be reduced further—it is already in its simplest irreducible form.

481/966

Step 5
