Answer 1

Answer: A

Explanation:

Notes: Dividing by a fraction means to multiply by its reciprocal.

The denominator cannot equal zero.

`(5a^3bc)/(8ab^3)/(-ab^2)/(6a^5b)\cdot (2a^2b^3)/(3b)\qquad \rightarrow a\\eq 0,b\\eq 0\\\\\\=(5a^3bc)/(8ab^3)\cdot(6a^5b)/(-ab^2)\cdot (2a^2b^3)/(3b)\\\\\\=(5\cdot 6\cdot 2\quad a^3\cdot a^5\cdot a^2\quad b\cdot b\cdot b^3\quad c)/(8\cdot -1 \cdot 3\quad a\cdot a\qquad b^3\cdot b^2\cdot b \quad)\\\\\\=(-60a^(10)b^5c)/(-24a^2b^6)\\\\\\=(-5a^8c)/(2b)`
