First, let's simplify each individual multiplication:

(-2 целых 2/5 - 1 целых 1/3) (-1 целых 17/28)
First, convert the mixed numbers to improper fractions:
(-12/5 - 4/3) (-45/28)
To add the fractions, we need a common denominator, which is 15 in this case:
(-36/15 - 20/15) (-45/28)
= (-56/15) (-45/28)
= 56/15 45/28
= 56 3 / 15 * 28
= 168/420
= 14/35
= 2/5

(5 целых 2/3 - 8 целых 3/4) (-8 целых 3/4 + 5 целых 2/3)
First, convert the mixed numbers to improper fractions:
(17/3 - 15/4) (-35/4 + 17/3)
To add the fractions, we need a common denominator, which is 12 in this case:
(68/12 - 45/12) (-105/12 + 68/12)
= (23/12) (-37/12)
= -23 37 / 12 12
= -851/144

Now, we can multiply the two results together:

(2/5) * (-851/144)
= -1702/720
= -851/360

Therefore, the final result is -851/360.
