What is 2/9 divided by 1/2? (Answer: 4/9)

Exact Answer

==================================================
Problem: What is 2/9 divided by 1/2?
Formula / Expression: 2/9 ÷ 1/2
Final Answer: 4/9
==================================================

Step-by-Step Solution:

Step 1: Find the Reciprocal of the Second Fraction
Dividing by a fraction is equivalent to multiplying by its reciprocal ("Keep, Change, Flip"). Invert the second fraction 1/2 to get 2/1.
Working: 2/9 ÷ 1/2 = 2/9 × 2

Step 2: Multiply the Numerators and Denominators
Multiply the new numerators (2 × 2 = 4) and denominators (9 × 1 = 9).
Working: 2 × 2/9 × 1 = 4/9

Step 3: Check if the Fraction Can Be Simplified
The Greatest Common Divisor (GCD) of 4 and 9 is 1, confirming that 4/9 cannot be reduced further—it is already in its simplest irreducible form.
Working: 4/9

Step 4: Decimal & Percentage Representation
Dividing the numerator 4 by denominator 9 produces a repeating decimal (approximately 0.444444, or 44.4444%).
Working: 4 ÷ 9 = 0.444444 (44.4444%)

Key Values:
- Simplified Fraction: 4/9
- Mixed Number Form: 4/9
- Decimal Value: 0.444444
