10 - 3 4/5 - 5 2/3
= 10 - 3 - 4/5 - 5 - 2/3= 7 - 9/5 - 5 - 2/3= 7 - 9/5 - 15/3 - 2/3= 7 - 9/5 - 30/15 - 10/15= 7 - (27 + 30)/15= 7 - 57/15= 7 - 3 12/15= 7 - 3 4/5= 3 1/5.
Итак, ответ равен 3 1/5.
10 - 3 4/5 - 5 2/3
= 10 - 3 - 4/5 - 5 - 2/3
= 7 - 9/5 - 5 - 2/3
= 7 - 9/5 - 15/3 - 2/3
= 7 - 9/5 - 30/15 - 10/15
= 7 - (27 + 30)/15
= 7 - 57/15
= 7 - 3 12/15
= 7 - 3 4/5
= 3 1/5.
Итак, ответ равен 3 1/5.
