What is 14/41 plus 9/13? (Answer: 551/533)

Exact Answer

==================================================
Problem: What is 14/41 plus 9/13?
Formula / Expression: 14/41 + 9/13
Final Answer: 1 18/533 (551/533)
==================================================

Step-by-Step Solution:

Step 1: Find the Least Common Denominator (LCD)
The denominators 41 and 13 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 41 × 13 = 533.
Working: LCD(41, 13) = 533

Step 2: Convert to Equivalent Fractions with Common Denominator 533
Multiply the numerator and denominator of 14/41 by 13, and multiply the numerator and denominator of 9/13 by 41 so both fractions share the common base 533.
Working: 14 × 13/41 × 13 = 182/533 and 9 × 41/13 × 41 = 369/533

Step 3: Add the Numerators
Now add the numerators (182 + 369 = 551) and keep the common denominator 533 unchanged.
Working: 182 + 369/533 = 551/533

Step 4: Check if the Fraction Can Be Simplified
The Greatest Common Divisor (GCD) of 551 and 533 is 1, confirming that 551/533 cannot be reduced further—it is already in its simplest irreducible form.
Working: 551/533

Step 5: Convert Improper Fraction to a Mixed Number
Since the numerator (551) is greater than the denominator (533), divide 551 by 533: it goes in 1 whole time(s) with a remainder of 18, giving the mixed number 1 18/533.
Working: 551/533 = 1 18/533

Step 6: Decimal & Percentage Representation
Dividing the numerator 551 by denominator 533 produces a repeating decimal (approximately 1.033771, or 103.3771%).
Working: 551 ÷ 533 = 1.033771 (103.3771%)

Key Values:
- Simplified Fraction: 551/533
- Mixed Number Form: 1 18/533
- Decimal Value: 1.033771
- Percentage: 103.3771%

Step-by-Step Solution: 14/41 + 9/13

Step 1

Find the Least Common Denominator (LCD)

The denominators 41 and 13 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 41 × 13 = 533.

LCD(41, 13) = 533

Step 2

Convert to Equivalent Fractions with Common Denominator 533

Multiply the numerator and denominator of 14/41 by 13, and multiply the numerator and denominator of 9/13 by 41 so both fractions share the common base 533.

14 × 13/41 × 13 = 182/533 and 9 × 41/13 × 41 = 369/533

Step 3

Add the Numerators

Now add the numerators (182 + 369 = 551) and keep the common denominator 533 unchanged.

182 + 369/533 = 551/533

Step 4

Check if the Fraction Can Be Simplified

The Greatest Common Divisor (GCD) of 551 and 533 is 1, confirming that 551/533 cannot be reduced further—it is already in its simplest irreducible form.

551/533

Step 5

Convert Improper Fraction to a Mixed Number

Since the numerator (551) is greater than the denominator (533), divide 551 by 533: it goes in 1 whole time(s) with a remainder of 18, giving the mixed number 1 18/533.

551/533 = 118/533

Step 6

Decimal & Percentage Representation

Dividing the numerator 551 by denominator 533 produces a repeating decimal (approximately 1.033771, or 103.3771%).

551 ÷ 533 = 1.033771 (103.3771%)
