What is 2/24 plus 8/39? (Answer: 15/52)

Exact Answer

==================================================
Problem: What is 2/24 plus 8/39?
Formula / Expression: 2/24 + 8/39
Final Answer: 15/52
==================================================

Step-by-Step Solution:

Step 1: Find the Least Common Denominator (LCD)
The denominators 24 and 39 share a common factor (GCD = 3). Finding their Least Common Multiple gives an LCD of 312 (which is smaller than their product 24 × 39 = 936, keeping the calculation simpler).
Working: LCD(24, 39) = 312

Step 2: Convert to Equivalent Fractions with Common Denominator 312
Multiply the numerator and denominator of 2/24 by 13, and multiply the numerator and denominator of 8/39 by 8 so both fractions share the common base 312.
Working: 2 × 13/24 × 13 = 26/312 and 8 × 8/39 × 8 = 64/312

Step 3: Add the Numerators
Now add the numerators (26 + 64 = 90) and keep the common denominator 312 unchanged.
Working: 26 + 64/312 = 90/312

Step 4: Simplify the Fraction to Lowest Terms
Find the Greatest Common Divisor (GCD) of 90 and 312, which is 6. Divide both the numerator and denominator by 6.
Working: 90 ÷ 6/312 ÷ 6 = 15/52

Step 5: Decimal & Percentage Representation
Dividing the numerator 15 by denominator 52 produces a repeating decimal (approximately 0.288462, or 28.8462%).
Working: 15 ÷ 52 = 0.288462 (28.8462%)

Key Values:
- Simplified Fraction: 15/52
- Mixed Number Form: 15/52
- Decimal Value: 0.288462
- Percentage: 28.8462%

Step-by-Step Solution: 2/24 + 8/39

Step 1

Find the Least Common Denominator (LCD)

The denominators 24 and 39 share a common factor (GCD = 3). Finding their Least Common Multiple gives an LCD of 312 (which is smaller than their product 24 × 39 = 936, keeping the calculation simpler).

LCD(24, 39) = 312

Step 2

Convert to Equivalent Fractions with Common Denominator 312

Multiply the numerator and denominator of 2/24 by 13, and multiply the numerator and denominator of 8/39 by 8 so both fractions share the common base 312.

2 × 13/24 × 13 = 26/312 and 8 × 8/39 × 8 = 64/312

Step 3

Add the Numerators

Now add the numerators (26 + 64 = 90) and keep the common denominator 312 unchanged.

26 + 64/312 = 90/312

Step 4

Simplify the Fraction to Lowest Terms

Find the Greatest Common Divisor (GCD) of 90 and 312, which is 6. Divide both the numerator and denominator by 6.

90 ÷ 6/312 ÷ 6 = 15/52

Step 5

Decimal & Percentage Representation

Dividing the numerator 15 by denominator 52 produces a repeating decimal (approximately 0.288462, or 28.8462%).

15 ÷ 52 = 0.288462 (28.8462%)
