Exact Answer

==================================================
Problem: What is 9/44 plus 6/21?
Formula / Expression: 9/44 + 6/21
Final Answer: 151/308
==================================================

Step-by-Step Solution:

Step 1: Find the Least Common Denominator (LCD)
The denominators 44 and 21 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 44 × 21 = 924.
Working: LCD(44, 21) = 924

Step 2: Convert to Equivalent Fractions with Common Denominator 924
Multiply the numerator and denominator of 9/44 by 21, and multiply the numerator and denominator of 6/21 by 44 so both fractions share the common base 924.
Working: 9 × 21/44 × 21 = 189/924 and 6 × 44/21 × 44 = 264/924

Step 3: Add the Numerators
Now add the numerators (189 + 264 = 453) and keep the common denominator 924 unchanged.
Working: 189 + 264/924 = 453/924

Step 4: Simplify the Fraction to Lowest Terms
Find the Greatest Common Divisor (GCD) of 453 and 924, which is 3. Divide both the numerator and denominator by 3.
Working: 453 ÷ 3/924 ÷ 3 = 151/308

Step 5: Decimal & Percentage Representation
Dividing the numerator 151 by denominator 308 produces a repeating decimal (approximately 0.49026, or 49.026%).
Working: 151 ÷ 308 = 0.49026 (49.026%)

Key Values:
- Simplified Fraction: 151/308
- Mixed Number Form: 151/308
- Decimal Value: 0.49026
- Percentage: 49.026%

Step-by-Step Solution: 9/44 + 6/21

Step 1

Find the Least Common Denominator (LCD)

The denominators 44 and 21 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 44 × 21 = 924.

LCD(44, 21) = 924

Step 2

Convert to Equivalent Fractions with Common Denominator 924

Multiply the numerator and denominator of 9/44 by 21, and multiply the numerator and denominator of 6/21 by 44 so both fractions share the common base 924.

9 × 21/44 × 21 = 189/924 and 6 × 44/21 × 44 = 264/924

Step 3

Add the Numerators

Now add the numerators (189 + 264 = 453) and keep the common denominator 924 unchanged.

189 + 264/924 = 453/924

Step 4

Simplify the Fraction to Lowest Terms

Find the Greatest Common Divisor (GCD) of 453 and 924, which is 3. Divide both the numerator and denominator by 3.

453 ÷ 3/924 ÷ 3 = 151/308

Step 5

Decimal & Percentage Representation

Dividing the numerator 151 by denominator 308 produces a repeating decimal (approximately 0.49026, or 49.026%).

151 ÷ 308 = 0.49026 (49.026%)
