mind helping??? really need it rn!!!!

Answer 1

Answer:-

$a) \: \: \: \frac{ - 6}{13} - ( \frac{ - 7}{15} )$

$= \frac{ - 6}{13} + \frac{7}{15}$

LCM of 13 and 15= 195

$= \frac{15( - 6) + 13(7)}{195}$

$= \frac{( - 90) +91 }{195}$

$= \frac{1}{195}$

$b) \: \: \: \frac{3}{7} \times \frac{( - 2)}{5}$

$= \frac{ 3×(-2)}{7×5}$

$= \frac{ - 6}{35}$

Answer 2

Step-by-step explanation:

lcm of 13 and 15= 195

-6/13 = -90/195

-7/15 = -91/195

=(-90/195)+91/195

=1/195

(-3×2)/(7×5)

-6/35

hope this helps
