Exact Answer

==================================================
Problem: What is 24/49 plus 9/13?
Formula / Expression: 24/49 + 9/13
Final Answer: 1 116/637 (753/637)
==================================================

Step-by-Step Solution:

Step 1: Find the Least Common Denominator (LCD)
The denominators 49 and 13 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 49 × 13 = 637.
Working: LCD(49, 13) = 637

Step 2: Convert to Equivalent Fractions with Common Denominator 637
Multiply the numerator and denominator of 24/49 by 13, and multiply the numerator and denominator of 9/13 by 49 so both fractions share the common base 637.
Working: 24 × 13/49 × 13 = 312/637 and 9 × 49/13 × 49 = 441/637

Step 3: Add the Numerators
Now add the numerators (312 + 441 = 753) and keep the common denominator 637 unchanged.
Working: 312 + 441/637 = 753/637

Step 4: Check if the Fraction Can Be Simplified
The Greatest Common Divisor (GCD) of 753 and 637 is 1, confirming that 753/637 cannot be reduced further—it is already in its simplest irreducible form.
Working: 753/637

Step 5: Convert Improper Fraction to a Mixed Number
Since the numerator (753) is greater than the denominator (637), divide 753 by 637: it goes in 1 whole time(s) with a remainder of 116, giving the mixed number 1 116/637.
Working: 753/637 = 1 116/637

Step 6: Decimal & Percentage Representation
Dividing the numerator 753 by denominator 637 produces a repeating decimal (approximately 1.182104, or 118.2104%).
Working: 753 ÷ 637 = 1.182104 (118.2104%)

Key Values:
- Simplified Fraction: 753/637
- Mixed Number Form: 1 116/637
- Decimal Value: 1.182104
- Percentage: 118.2104%

Step-by-Step Solution: 24/49 + 9/13

Step 1

Find the Least Common Denominator (LCD)

The denominators 49 and 13 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 49 × 13 = 637.

LCD(49, 13) = 637

Step 2

Convert to Equivalent Fractions with Common Denominator 637

Multiply the numerator and denominator of 24/49 by 13, and multiply the numerator and denominator of 9/13 by 49 so both fractions share the common base 637.

24 × 13/49 × 13 = 312/637 and 9 × 49/13 × 49 = 441/637

Step 3

Add the Numerators

Now add the numerators (312 + 441 = 753) and keep the common denominator 637 unchanged.

312 + 441/637 = 753/637

Step 4

Check if the Fraction Can Be Simplified
