What is 14/33 plus 9/13? (Answer: 479/429)

Exact Answer

==================================================
Problem: What is 14/33 plus 9/13?
Formula / Expression: 14/33 + 9/13
Final Answer: 1 50/429 (479/429)
==================================================

Step-by-Step Solution:

Step 1: Find the Least Common Denominator (LCD)
The denominators 33 and 13 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 33 × 13 = 429.
Working: LCD(33, 13) = 429

Step 2: Convert to Equivalent Fractions with Common Denominator 429
Multiply the numerator and denominator of 14/33 by 13, and multiply the numerator and denominator of 9/13 by 33 so both fractions share the common base 429.
Working: 14 × 13/33 × 13 = 182/429 and 9 × 33/13 × 33 = 297/429

Step 3: Add the Numerators
Now add the numerators (182 + 297 = 479) and keep the common denominator 429 unchanged.
Working: 182 + 297/429 = 479/429

Step 4: Check if the Fraction Can Be Simplified
The Greatest Common Divisor (GCD) of 479 and 429 is 1, confirming that 479/429 cannot be reduced further—it is already in its simplest irreducible form.
Working: 479/429

Step 5: Convert Improper Fraction to a Mixed Number
Since the numerator (479) is greater than the denominator (429), divide 479 by 429: it goes in 1 whole time(s) with a remainder of 50, giving the mixed number 1 50/429.
Working: 479/429 = 1 50/429

Step 6: Decimal & Percentage Representation
Dividing the numerator 479 by denominator 429 produces a repeating decimal (approximately 1.11655, or 111.655%).
Working: 479 ÷ 429 = 1.11655 (111.655%)

Key Values:
- Simplified Fraction: 479/429
- Mixed Number Form: 1 50/429
- Decimal Value: 1.11655
- Percentage: 111.655%

Step-by-Step Solution: 14/33 + 9/13

Step 1

Find the Least Common Denominator (LCD)

The denominators 33 and 13 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 33 × 13 = 429.

LCD(33, 13) = 429

Step 2

Convert to Equivalent Fractions with Common Denominator 429

Multiply the numerator and denominator of 14/33 by 13, and multiply the numerator and denominator of 9/13 by 33 so both fractions share the common base 429.

14 × 13/33 × 13 = 182/429 and 9 × 33/13 × 33 = 297/429

Step 3

Add the Numerators

Now add the numerators (182 + 297 = 479) and keep the common denominator 429 unchanged.

182 + 297/429 = 479/429

Step 4

Check if the Fraction Can Be Simplified

The Greatest Common Divisor (GCD) of 479 and 429 is 1, confirming that 479/429 cannot be reduced further—it is already in its simplest irreducible form.

479/429

Step 5

Convert Improper Fraction to a Mixed Number
