Answer:

Step-by-step explanation:

Convert mixed fraction to improper fraction and then multiply

$-2 \frac{1}{4}=- \frac{2*4+1}{4} = -\frac{9}{4}\\\\6 \frac{8}{9}= \frac{6*9+8}{9} = \frac{62}{9}\\\\-2\frac{1}{4}* 6\frac{8}{9} = \frac{-9}{4} * \frac{62}{9}\\\\= \frac{-31}{2}\\\\= -15 \frac{1}{2}$

Answer:

$\large\boxed{(9x^2y^3)(12x^{-3}y^5)(2xy)=216y^9}\to\boxed{B.}$

Step-by-step explanation:

$(9x^2y^3)(12x^{-3}y^5)(2xy)=(9\cdot12\cdot2)(x^2x^{-3}x)(y^3y^5y)\\\\\text{Use}\ a^n\cdot a^m=a^{n+m}\\\\=216x^{2+(-3)+1}y^{3+5+1}=216x^0y^9\\\\\text{Use}\ a^0=1\ \text{for any value of}\ a\ \text{except 0}\\\\=216y^9$
