What is 5/24 plus 3/9? (Answer: 13/24)

Exact Answer

==================================================
Problem: What is 5/24 plus 3/9?
Formula / Expression: 5/24 + 3/9
Final Answer: 13/24
==================================================

Step-by-Step Solution:

Step 1: Find the Least Common Denominator (LCD)
The denominators 24 and 9 share a common factor (GCD = 3). Finding their Least Common Multiple gives an LCD of 72 (which is smaller than their product 24 × 9 = 216, keeping the calculation simpler).
Working: LCD(24, 9) = 72

Step 2: Convert to Equivalent Fractions with Common Denominator 72
Multiply the numerator and denominator of 5/24 by 3, and multiply the numerator and denominator of 3/9 by 8 so both fractions share the common base 72.
Working: 5 × 3/24 × 3 = 15/72 and 3 × 8/9 × 8 = 24/72

Step 3: Add the Numerators
Now add the numerators (15 + 24 = 39) and keep the common denominator 72 unchanged.
Working: 15 + 24/72 = 39/72

Step 4: Simplify the Fraction to Lowest Terms
Find the Greatest Common Divisor (GCD) of 39 and 72, which is 3. Divide both the numerator and denominator by 3.
Working: 39 ÷ 3/72 ÷ 3 = 13/24

Step 5: Decimal & Percentage Representation
Dividing the numerator 13 by denominator 24 produces a repeating decimal (approximately 0.541667, or 54.1667%).
Working: 13 ÷ 24 = 0.541667 (54.1667%)

Key Values:
- Simplified Fraction: 13/24
- Mixed Number Form: 13/24
- Decimal Value: 0.541667
- Percentage: 54.1667%

The denominators 24 and 9 share a common factor (GCD = 3). Finding their Least Common Multiple gives an LCD of 72 (which is smaller than their product 24 × 9 = 216, keeping the calculation simpler).

LCD(24, 9) = 72

Step 2

Convert to Equivalent Fractions with Common Denominator 72

Multiply the numerator and denominator of 5/24 by 3, and multiply the numerator and denominator of 3/9 by 8 so both fractions share the common base 72.

5 × 3/24 × 3 = 15/72 and 3 × 8/9 × 8 = 24/72

Step 3

Add the Numerators

Now add the numerators (15 + 24 = 39) and keep the common denominator 72 unchanged.

15 + 24/72 = 39/72

Step 4

Simplify the Fraction to Lowest Terms

Find the Greatest Common Divisor (GCD) of 39 and 72, which is 3. Divide both the numerator and denominator by 3.

39 ÷ 3/72 ÷ 3 = 13/24

Step 5
