Exact Answer

==================================================
Problem: What is 14/24 plus 9/13?
Formula / Expression: 14/24 + 9/13
Final Answer: 1 43/156 (199/156)
==================================================

Step-by-Step Solution:

Step 1: Find the Least Common Denominator (LCD)
The denominators 24 and 13 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 24 × 13 = 312.
Working: LCD(24, 13) = 312

Step 2: Convert to Equivalent Fractions with Common Denominator 312
Multiply the numerator and denominator of 14/24 by 13, and multiply the numerator and denominator of 9/13 by 24 so both fractions share the common base 312.
Working: 14 × 13/24 × 13 = 182/312 and 9 × 24/13 × 24 = 216/312

Step 3: Add the Numerators
Now add the numerators (182 + 216 = 398) and keep the common denominator 312 unchanged.
Working: 182 + 216/312 = 398/312

Step 4: Simplify the Fraction to Lowest Terms
Find the Greatest Common Divisor (GCD) of 398 and 312, which is 2. Divide both the numerator and denominator by 2.
Working: 398 ÷ 2/312 ÷ 2 = 199/156

Step 5: Convert Improper Fraction to a Mixed Number
Since the numerator (199) is greater than the denominator (156), divide 199 by 156: it goes in 1 whole time(s) with a remainder of 43, giving the mixed number 1 43/156.
Working: 199/156 = 1 43/156

Step 6: Decimal & Percentage Representation
Dividing the numerator 199 by denominator 156 produces a repeating decimal (approximately 1.275641, or 127.5641%).
Working: 199 ÷ 156 = 1.275641 (127.5641%)

Key Values:
- Simplified Fraction: 199/156
- Mixed Number Form: 1 43/156
- Decimal Value: 1.275641
- Percentage: 127.5641%

Step-by-Step Solution: 14/24 + 9/13

Step 1

Find the Least Common Denominator (LCD)

The denominators 24 and 13 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 24 × 13 = 312.

LCD(24, 13) = 312

Step 2

Convert to Equivalent Fractions with Common Denominator 312

Multiply the numerator and denominator of 14/24 by 13, and multiply the numerator and denominator of 9/13 by 24 so both fractions share the common base 312.

14 × 13/24 × 13 = 182/312 and 9 × 24/13 × 24 = 216/312

Step 3

Add the Numerators

Now add the numerators (182 + 216 = 398) and keep the common denominator 312 unchanged.

182 + 216/312 = 398/312

Step 4

Simplify the Fraction to Lowest Terms

Find the Greatest Common Divisor (GCD) of 398 and 312, which is 2. Divide both the numerator and denominator by 2.

398 ÷ 2/312 ÷ 2 = 199/156

Step 5

Convert Improper Fraction to a Mixed Number

Since the numerator (199) is greater than the denominator (156), divide 199 by 156: it goes in 1 whole time(s) with a remainder of 43, giving the mixed number 1 43/156.

199/156 = 143/156

Step 6

Decimal & Percentage Representation

Dividing the numerator 199 by denominator 156 produces a repeating decimal (approximately 1.275641, or 127.5641%).

199 ÷ 156 = 1.275641 (127.5641%)
