Exact Answer

==================================================
Problem: What is 5/24 plus 2/7?
Formula / Expression: 5/24 + 2/7
Final Answer: 83/168
==================================================

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 5/24 by 7, and multiply the numerator and denominator of 2/7 by 24 so both fractions share the common base 168.
Working: 5 × 7/24 × 7 = 35/168 and 2 × 24/7 × 24 = 48/168

Step 3: Add the Numerators
Now add the numerators (35 + 48 = 83) and keep the common denominator 168 unchanged.
Working: 35 + 48/168 = 83/168

Step 4: Check if the Fraction Can Be Simplified
The Greatest Common Divisor (GCD) of 83 and 168 is 1, confirming that 83/168 cannot be reduced further—it is already in its simplest irreducible form.
Working: 83/168

Step 5: Decimal & Percentage Representation
Dividing the numerator 83 by denominator 168 produces a repeating decimal (approximately 0.494048, or 49.4048%).
Working: 83 ÷ 168 = 0.494048 (49.4048%)

Key Values:
- Simplified Fraction: 83/168
- Mixed Number Form: 83/168
- Decimal Value: 0.494048

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 5/24 by 7, and multiply the numerator and denominator of 2/7 by 24 so both fractions share the common base 168.

5 × 7/24 × 7 = 35/168 and 2 × 24/7 × 24 = 48/168

Step 3

Add the Numerators

Now add the numerators (35 + 48 = 83) and keep the common denominator 168 unchanged.

35 + 48/168 = 83/168

Step 4

Check if the Fraction Can Be Simplified

The Greatest Common Divisor (GCD) of 83 and 168 is 1, confirming that 83/168 cannot be reduced further—it is already in its simplest irreducible form.
