Answer 1

- 2 3/5 - 1 2/3

= -2 9/15 - 1 10/15

= (-2 9/15) + (- 1 10/15)

= -3 19/15

= -4 4/15

Answer is B

-4 4/15

Answer 2

$-2\dfrac{3}{5}-1\dfrac{2}{3}\\\\\text{the common denominator is 15}\\\\-2\dfrac{3\cdot3}{5\cdot3}-1\dfrac{2\cdot5}{3\cdot5}=-2\dfrac{9}{15}-1\dfrac{10}{15}=-\left(2\dfrac{9}{15}+1\dfrac{10}{15}\right)=-3\dfrac{19}{15}\\\\=\boxed{-4\dfrac{4}{15}}\to\boxed{b.}$
