What is 5/24 plus 2/5? (Answer: 73/120)

Exact Answer

==================================================
Problem: What is 5/24 plus 2/5?
Formula / Expression: 5/24 + 2/5
Final Answer: 73/120
==================================================

Step-by-Step Solution:

Step 1: Find the Least Common Denominator (LCD)
The denominators 24 and 5 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 24 × 5 = 120.
Working: LCD(24, 5) = 120

Step 2: Convert to Equivalent Fractions with Common Denominator 120
Multiply the numerator and denominator of 5/24 by 5, and multiply the numerator and denominator of 2/5 by 24 so both fractions share the common base 120.
Working: 5 × 5/24 × 5 = 25/120 and 2 × 24/5 × 24 = 48/120

Step 3: Add the Numerators
Now add the numerators (25 + 48 = 73) and keep the common denominator 120 unchanged.
Working: 25 + 48/120 = 73/120

Step 4: Check if the Fraction Can Be Simplified
The Greatest Common Divisor (GCD) of 73 and 120 is 1, confirming that 73/120 cannot be reduced further—it is already in its simplest irreducible form.
Working: 73/120

Step 5: Decimal & Percentage Representation
Dividing the numerator 73 by denominator 120 produces a repeating decimal (approximately 0.608333, or 60.8333%).
Working: 73 ÷ 120 = 0.608333 (60.8333%)

Key Values:
- Simplified Fraction: 73/120
- Mixed Number Form: 73/120
- Decimal Value: 0.608333
- Percentage: 60.8333%

Step-by-Step Solution: 5/24 + 2/5

Step 1

Find the Least Common Denominator (LCD)

The denominators 24 and 5 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 24 × 5 = 120.

LCD(24, 5) = 120

Step 2

Convert to Equivalent Fractions with Common Denominator 120

Multiply the numerator and denominator of 5/24 by 5, and multiply the numerator and denominator of 2/5 by 24 so both fractions share the common base 120.

5 × 5/24 × 5 = 25/120 and 2 × 24/5 × 24 = 48/120

Step 3

Add the Numerators

Now add the numerators (25 + 48 = 73) and keep the common denominator 120 unchanged.

25 + 48/120 = 73/120

Step 4

Check if the Fraction Can Be Simplified

The Greatest Common Divisor (GCD) of 73 and 120 is 1, confirming that 73/120 cannot be reduced further—it is already in its simplest irreducible form.

73/120

Step 5

Decimal & Percentage Representation

Dividing the numerator 73 by denominator 120 produces a repeating decimal (approximately 0.608333, or 60.8333%).
