What is 4/24 plus 2/9? (Answer: 7/18)

Exact Answer

==================================================
Problem: What is 4/24 plus 2/9?
Formula / Expression: 4/24 + 2/9
Final Answer: 7/18
==================================================

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 4/24 by 3, and multiply the numerator and denominator of 2/9 by 8 so both fractions share the common base 72.
Working: 4 × 3/24 × 3 = 12/72 and 2 × 8/9 × 8 = 16/72

Step 3: Add the Numerators
Now add the numerators (12 + 16 = 28) and keep the common denominator 72 unchanged.
Working: 12 + 16/72 = 28/72

Step 4: Simplify the Fraction to Lowest Terms
Find the Greatest Common Divisor (GCD) of 28 and 72, which is 4. Divide both the numerator and denominator by 4.
Working: 28 ÷ 4/72 ÷ 4 = 7/18

Step 5: Decimal & Percentage Representation
Dividing the numerator 7 by denominator 18 produces a repeating decimal (approximately 0.388889, or 38.8889%).
Working: 7 ÷ 18 = 0.388889 (38.8889%)

Key Values:
- Simplified Fraction: 7/18
- Mixed Number Form: 7/18
- Decimal Value: 0.388889
- Percentage: 38.8889%

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 4/24 by 3, and multiply the numerator and denominator of 2/9 by 8 so both fractions share the common base 72.

4 × 3/24 × 3 = 12/72 and 2 × 8/9 × 8 = 16/72

Step 3

Add the Numerators

Now add the numerators (12 + 16 = 28) and keep the common denominator 72 unchanged.

12 + 16/72 = 28/72

Step 4

Simplify the Fraction to Lowest Terms

Find the Greatest Common Divisor (GCD) of 28 and 72, which is 4. Divide both the numerator and denominator by 4.

28 ÷ 4/72 ÷ 4 = 7/18
