Exact Answer

==================================================
Problem: What is 10/21 plus 22/46?
Formula / Expression: 10/21 + 22/46
Final Answer: 461/483
==================================================

Step-by-Step Solution:

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

Step 2: Convert to Equivalent Fractions with Common Denominator 966
Multiply the numerator and denominator of 10/21 by 46, and multiply the numerator and denominator of 22/46 by 21 so both fractions share the common base 966.
Working: 10 × 46/21 × 46 = 460/966 and 22 × 21/46 × 21 = 462/966

Step 3: Add the Numerators
Now add the numerators (460 + 462 = 922) and keep the common denominator 966 unchanged.
Working: 460 + 462/966 = 922/966

Step 4: Simplify the Fraction to Lowest Terms
Find the Greatest Common Divisor (GCD) of 922 and 966, which is 2. Divide both the numerator and denominator by 2.
Working: 922 ÷ 2/966 ÷ 2 = 461/483

Step 5: Decimal & Percentage Representation
Dividing the numerator 461 by denominator 483 produces a repeating decimal (approximately 0.954451, or 95.4451%).
Working: 461 ÷ 483 = 0.954451 (95.4451%)

Key Values:
- Simplified Fraction: 461/483
- Mixed Number Form: 461/483
- Decimal Value: 0.954451
- Percentage: 95.4451%

Step-by-Step Solution: 10/21 + 22/46

Step 1

Find the Least Common Denominator (LCD)

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

LCD(21, 46) = 966

Step 2

Convert to Equivalent Fractions with Common Denominator 966

Multiply the numerator and denominator of 10/21 by 46, and multiply the numerator and denominator of 22/46 by 21 so both fractions share the common base 966.

10 × 46/21 × 46 = 460/966 and 22 × 21/46 × 21 = 462/966

Step 3

Add the Numerators

Now add the numerators (460 + 462 = 922) and keep the common denominator 966 unchanged.

460 + 462/966 = 922/966

Step 4

Simplify the Fraction to Lowest Terms

Find the Greatest Common Divisor (GCD) of 922 and 966, which is 2. Divide both the numerator and denominator by 2.

922 ÷ 2/966 ÷ 2 = 461/483

Step 5

Decimal & Percentage Representation

Dividing the numerator 461 by denominator 483 produces a repeating decimal (approximately 0.954451, or 95.4451%).

461 ÷ 483 = 0.954451 (95.4451%)
