What is 3/9 divided by 2/4? (Answer: 2/3)

Exact Answer

==================================================
Problem: What is 3/9 divided by 2/4?
Formula / Expression: 3/9 ÷ 2/4
Final Answer: 2/3
==================================================

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 2/4 to get 4/2.
Working: 3/9 ÷ 2/4 = 3/9 × 4/2

Step 2: Multiply the Numerators and Denominators
Multiply the new numerators (3 × 4 = 12) and denominators (9 × 2 = 18).
Working: 3 × 4/9 × 2 = 12/18

Step 3: Simplify the Fraction to Lowest Terms
Find the Greatest Common Divisor (GCD) of 12 and 18, which is 6. Divide both the numerator and denominator by 6.
Working: 12 ÷ 6/18 ÷ 6 = 2/3

Step 4: Decimal & Percentage Representation
Dividing the numerator 2 by denominator 3 produces a repeating decimal (approximately 0.666667, or 66.6667%).
Working: 2 ÷ 3 = 0.666667 (66.6667%)

Key Values:
- Simplified Fraction: 2/3
- Mixed Number Form: 2/3
- Decimal Value: 0.666667
