Exact Answer

==================================================
Problem: What is 2/13 divided by 9/21?
Formula / Expression: 2/13 ÷ 9/21
Final Answer: 14/39
==================================================

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 9/21 to get 21/9.
Working: 2/13 ÷ 9/21 = 2/13 × 21/9

Step 2: Multiply the Numerators and Denominators
Multiply the new numerators (2 × 21 = 42) and denominators (13 × 9 = 117).
Working: 2 × 21/13 × 9 = 42/117

Step 3: Simplify the Fraction to Lowest Terms
Find the Greatest Common Divisor (GCD) of 42 and 117, which is 3. Divide both the numerator and denominator by 3.
Working: 42 ÷ 3/117 ÷ 3 = 14/39

Step 4: Decimal & Percentage Representation
Dividing the numerator 14 by denominator 39 produces a repeating decimal (approximately 0.358974, or 35.8974%).
Working: 14 ÷ 39 = 0.358974 (35.8974%)
