Exact Answer

==================================================
Problem: What is 2/24 plus 7/9?
Formula / Expression: 2/24 + 7/9
Final Answer: 31/36
==================================================

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 2/24 by 3, and multiply the numerator and denominator of 7/9 by 8 so both fractions share the common base 72.
Working: 2 × 3/24 × 3 = 6/72 and 7 × 8/9 × 8 = 56/72

Step 3: Add the Numerators
Now add the numerators (6 + 56 = 62) and keep the common denominator 72 unchanged.
Working: 6 + 56/72 = 62/72

Step 4: Simplify the Fraction to Lowest Terms
Find the Greatest Common Divisor (GCD) of 62 and 72, which is 2. Divide both the numerator and denominator by 2.
Working: 62 ÷ 2/72 ÷ 2 = 31/36

Step 5: Decimal & Percentage Representation
Dividing the numerator 31 by denominator 36 produces a repeating decimal (approximately 0.861111, or 86.1111%).
Working: 31 ÷ 36 = 0.861111 (86.1111%)

Key Values:
- Simplified Fraction: 31/36
- Mixed Number Form: 31/36
- Decimal Value: 0.861111
- Percentage: 86.1111%
