Exact Answer

==================================================
Problem: What is 9/24 plus 4/7?
Formula / Expression: 9/24 + 4/7
Final Answer: 53/56
==================================================

Step-by-Step Solution:

Step 1: Find the Least Common Denominator (LCD)
The denominators 24 and 7 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 24 × 7 = 168.
Working: LCD(24, 7) = 168

Step 2: Convert to Equivalent Fractions with Common Denominator 168
Multiply the numerator and denominator of 9/24 by 7, and multiply the numerator and denominator of 4/7 by 24 so both fractions share the common base 168.
Working: 9 × 7/24 × 7 = 63/168 and 4 × 24/7 × 24 = 96/168

Step 3: Add the Numerators
Now add the numerators (63 + 96 = 159) and keep the common denominator 168 unchanged.
Working: 63 + 96/168 = 159/168

Step 4: Simplify the Fraction to Lowest Terms
Find the Greatest Common Divisor (GCD) of 159 and 168, which is 3. Divide both the numerator and denominator by 3.
Working: 159 ÷ 3/168 ÷ 3 = 53/56

Step 5: Decimal & Percentage Representation
Dividing the numerator 53 by denominator 56 produces a repeating decimal (approximately 0.946429, or 94.6429%).
Working: 53 ÷ 56 = 0.946429 (94.6429%)

Key Values:
- Simplified Fraction: 53/56
- Mixed Number Form: 53/56
- Decimal Value: 0.946429
- Percentage: 94.6429%

Step-by-Step Solution: 9/24 + 4/7

Step 1

Find the Least Common Denominator (LCD)

The denominators 24 and 7 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 24 × 7 = 168.

LCD(24, 7) = 168

Step 2

Convert to Equivalent Fractions with Common Denominator 168

Multiply the numerator and denominator of 9/24 by 7, and multiply the numerator and denominator of 4/7 by 24 so both fractions share the common base 168.

9 × 7/24 × 7 = 63/168 and 4 × 24/7 × 24 = 96/168

Step 3

Add the Numerators

Now add the numerators (63 + 96 = 159) and keep the common denominator 168 unchanged.

63 + 96/168 = 159/168

Step 4

Simplify the Fraction to Lowest Terms

Find the Greatest Common Divisor (GCD) of 159 and 168, which is 3. Divide both the numerator and denominator by 3.

159 ÷ 3/168 ÷ 3 = 53/56

Step 5

Decimal & Percentage Representation

Dividing the numerator 53 by denominator 56 produces a repeating decimal (approximately 0.946429, or 94.6429%).

53 ÷ 56 = 0.946429 (94.6429%)
