Answer 2

Step-by-step explanation:

$(\frac{ - 12}{13} \times \frac{7}{4} ) - (\frac{ - 1}{3} \times \frac{ - 5}{7} )$

so in first bracket

4 1za and 4 3za

and second

nothing to change

di

$\frac{ - 21}{13} - \frac{5}{21}$

so lcm of 13and 21 is 273

so

$\frac{ - 273 - 65}{273}$

$\frac{338}{273}$
