Q. Divide. Simplify your answer.\newline20d9c2÷16cd219cd2\frac{20d}{9c^2} \div \frac{16cd^2}{19cd^2}\newline______
  1. Rewrite division as multiplication: Write the division of the two fractions as a multiplication by the reciprocal of the second fraction.\newlineWe have: (20d9c2)÷(16cd219cd2)(\frac{20d}{9c^2}) \div (\frac{16cd^2}{19cd^2})\newlineThis can be rewritten as: (20d9c2)×(19cd216cd2)(\frac{20d}{9c^2}) \times (\frac{19cd^2}{16cd^2})
  2. Simplify second fraction: Simplify the second fraction before multiplying.\newlineThe cd2cd^2 terms in the numerator and denominator of the second fraction cancel each other out.\newlineSo, (19cd2/16cd2)(19cd^2/16cd^2) simplifies to (19/16)(19/16)
  3. Multiply fractions: Multiply the first fraction by the simplified second fraction.\newline(20d9c2)×(1916)=20d×199c2×16(\frac{20d}{9c^2}) \times (\frac{19}{16}) = \frac{20d \times 19}{9c^2 \times 16}
  4. Perform multiplication: Perform the multiplication in the numerator and the denominator.\newline(20d×19)/(9c2×16)=(380d)/(144c2)(20d \times 19)/(9c^2 \times 16) = (380d)/(144c^2)
  5. Simplify final fraction: Simplify the fraction by dividing both the numerator and the denominator by their greatest common divisor, if possible.\newlineThe greatest common divisor of 380380 and 144144 is 44.\newline380d144c2\frac{380d}{144c^2} = 95d36c2\frac{95d}{36c^2}
