Answer 2

$\frac{21x {}^{3}y }{8p {}^{2} } \div ( - 3xy {}^{3} ) = - \frac{21x {}^{3} y \times}{8p {}^{2} \times 3xy {}^{3} } = \frac{7x {}^{2} }{8p {}^{2} \times y {}^{2} } = \frac{7x {}^{2} }{8p {}^{2} y {}^{2} }$

$\frac{p - 4}{20m {}^{3} } \div \frac{1 - 4p {}^{2} }{25m {}^{2} } = \frac{p - 4 \times 25m {}^{2} }{20m {}^{3} \times 1 - 4p {}^{2} } = \frac{p - 4 \times 5}{4m \times 1 - 4p {}^{2} } = \frac{5(p - 4)}{4m(1 - 4p {}^{2}) } = \frac{5p - 20}{4m - 16mp {}^{2} }$
