Question

(iv) Divide the sum of 13/5 and (-12)/7 by the product of (-13)/7 and 1/(-2)​

Answer 1

Step-by-step explanation:

$\frac{13}{5} + \frac{ - 12}{7}$

$\frac{91 - 60}{35}$

$\frac{31}{35}$

$\frac{ - 13}{7} \times \frac{ - 1}{2}$

$\frac{13}{14}$

$\frac{31}{35} \div \frac{13}{14}$

$\frac{31}{35} \times \frac{14}{13}$

$\frac{31}{5} \times \frac{2}{13}$

$= \frac{62}{65}$
