Simplify :

$\Large\tt( - \frac{8}{5} \times \frac{3}{4}) + ( \frac{7}{8} \times \frac{ - 16}{ \: \: \: 25} )$

$\huge\bold\purple{♡\:} {\orange{\underline{\pink{\mathfrak{ Solution}}}}} \bold\purple{\:♡}$

$\Large\longrightarrow$$\Large\tt( - \frac{8}{5} \times \frac{3}{4}) + ( \frac{7}{8} \times \frac{ - 16}{ \: \: \: 25} )$

$\Large\longrightarrow$$\Large\tt ( - \frac{2}{5} \times 3) + ( - \frac{7}{8} \times \frac{16}{25} )$

$\Large\longrightarrow$$\Large\tt ( - \frac{2}{3} \times 3) + ( - 7 \times \frac{2}{25} )$

$\Large\longrightarrow$$\Large\tt ( - \frac{6}{5} ) + ( - 7 \times \frac{2}{25} )$

$\Large\longrightarrow$$\Large\tt( - \frac{6}{5} ) + ( - \frac{14}{25})$

$\Large\longrightarrow$$\Large\tt - \frac{6}{5} + ( - \frac{14}{25} )$

$\Large\longrightarrow$$\Large\tt - \frac{6}{5} - \frac{14}{25}$

$\Large\longrightarrow$$\Large\tt - \frac{44}{25}$

Answer 2

$\frac{ - 8}{5} \times \frac{3}{4}$

$\frac{ - 8}{5} \times \frac{3}{4} \\ = \frac{ - 24}{15}$

$\\ \frac{ 7}{8} \times \frac{ - 16}{24}$

$\frac{ -14}{25}$

$\frac{ - 24}{15} + \frac{ - 14}{25}$

$= \frac{ - 162}{75}$

$\frac{ - 44}{25}$
