af scation numbro, evaluate the
fallowing: 1) 3/13 × 4/5 - 7/5 - 4/5 × 5/13 2) 5/7 + 2/11 + -8/7 + 6/10​

Answer 1

$\LARGE \underline{ \underline{ \sf \green{ Solution:}}}$

$\longrightarrow \tt \frac{3}{13} \times \frac{4}{5} - \frac{7}{5} - \frac{4}{5} \times \frac{5}{13} \\ \\\longrightarrow \tt \frac{12}{65} - \frac{7}{5} - \frac{4}{13} \\ \\\longrightarrow \tt \frac{12 - 91 - 20}{65} \\ \\ \longrightarrow\tt \frac{ - 99}{65}$
