Помогите пожалуйста с примером.
48: 6 2/5 - (18: 5 2/5 + 2/3) * 2/3

Answer 1

48÷6.2/5-(18÷5.2/5+2/3)×2/3=
=48÷32/5-(18÷27/5+2/3)×2/3=
=48÷5/32-(18÷5/27+2/3)×2/3=
=30/4-(10/3+2/3)×2/3=
=7.1/2-(3.1/3+2/3)×2/3=
=7.1/2-(4×2/3)=
=7.1/2-8/3=
=7.1/2-2.2/3=
=5. (3-4)/6=
=4. (6+3-4)/6=
=4.5/6
Ответ:4.5/6 (4 целых 5/6)
