Answer 1

-3 3/8*(-1 7/9) =1,89
-12,6*0,7+4,8*(-1,7)=12,45

Answer 2

I can help you with math problems. Here are the detailed solutions for your questions:

1) $$-3+\frac{3}{8}+\left(-1+\frac{7}{9}\right) = -3+\frac{3}{8}-\frac{2}{9}$$ $$= -\frac{27}{8}-\frac{2}{9} = -\frac{81}{72}-\frac{16}{72} = -\frac{97}{72}$$

2) $$-12.6\times 0.7+4.8\times (-1.7) = -8.82-8.16 = -16.98$$

I hope this helps. If you have any other questions, feel free to ask me.
