Answer 2

Answer:

3) -36/35

4) 8/35

Step-by-step explanation:

3) What should be added to -3/5 to get 3/7?

--) -3/5 + [] = 3/7

[] = 3/7 - (-3)/5

[] = 15/35 - (-21)/35

[] = 15-(-21)/35

[] = -36/35

therefore -36/35 should be added.

4) -8/14x6/-15

$\frac{ - 8}{14} \times \frac{6}{ - 15}$

$\frac{ - 4}{7} \times \frac{2}{ - 5}$

$\frac{ - 8}{ - 35}$

= 8/35
