What is 1/24 plus 2/3? (Answer: 17/24)

Exact Answer

==================================================
Problem: What is 1/24 plus 2/3?
Formula / Expression: 1/24 + 2/3
Final Answer: 17/24
==================================================

Step-by-Step Solution:

Step 1: Find the Least Common Denominator (LCD)
Notice that 24 is an exact multiple of 3 (3 × 8 = 24). The Least Common Denominator (LCD) is simply 24, meaning we only need to scale one fraction.
Working: LCD(24, 3) = 24

Step 2: Convert to Equivalent Fractions with Common Denominator 24
Multiply the numerator and denominator of 1/24 by 1, and multiply the numerator and denominator of 2/3 by 8 so both fractions share the common base 24.
Working: 1 × 1/24 × 1 = 1/24 and 2 × 8/3 × 8 = 16/24

Step 3: Add the Numerators
Now add the numerators (1 + 16 = 17) and keep the common denominator 24 unchanged.
Working: 1 + 16/24 = 17/24

Step 4: Check if the Fraction Can Be Simplified
The Greatest Common Divisor (GCD) of 17 and 24 is 1, confirming that 17/24 cannot be reduced further—it is already in its simplest irreducible form.
Working: 17/24

Step 5: Decimal & Percentage Representation
Dividing the numerator 17 by denominator 24 produces a repeating decimal (approximately 0.708333, or 70.8333%).
Working: 17 ÷ 24 = 0.708333 (70.8333%)

Key Values:
- Simplified Fraction: 17/24
- Mixed Number Form: 17/24
- Decimal Value: 0.708333
- Percentage: 70.8333%

Step-by-Step Solution: 1/24 + 2/3

Step 1

Find the Least Common Denominator (LCD)

Notice that 24 is an exact multiple of 3 (3 × 8 = 24). The Least Common Denominator (LCD) is simply 24, meaning we only need to scale one fraction.

LCD(24, 3) = 24

Step 2

Convert to Equivalent Fractions with Common Denominator 24

Multiply the numerator and denominator of 1/24 by 1, and multiply the numerator and denominator of 2/3 by 8 so both fractions share the common base 24.

1 × 1/24 × 1 = 1/24 and 2 × 8/3 × 8 = 16/24

Step 3

Add the Numerators

Now add the numerators (1 + 16 = 17) and keep the common denominator 24 unchanged.

1 + 16/24 = 17/24

Step 4

Check if the Fraction Can Be Simplified

The Greatest Common Divisor (GCD) of 17 and 24 is 1, confirming that 17/24 cannot be reduced further—it is already in its simplest irreducible form.
