Вопрос:

73. Вычисли значение каждого выражения. 32:8:2⋅6:3= 16:8⋅7+66= 30:5+3⋅9= 24:4+5⋅2= 28:7⋅4:8⋅3= 40:4+36:4= 12:4+24:3= 24:4⋅2:6=

Ответ:

  • 32 : 8 : 2 ⋅ 6 : 3 = 4 : 2 ⋅ 6 : 3 = 2 ⋅ 6 : 3 = 12 : 3 = 4
  • 16 : 8 ⋅ 7 + 66 = 2 ⋅ 7 + 66 = 14 + 66 = 80
  • 30 : 5 + 3 ⋅ 9 = 6 + 3 ⋅ 9 = 6 + 27 = 33
  • 24 : 4 + 5 ⋅ 2 = 6 + 5 ⋅ 2 = 6 + 10 = 16
  • 28 : 7 ⋅ 4 : 8 ⋅ 3 = 4 ⋅ 4 : 8 ⋅ 3 = 16 : 8 ⋅ 3 = 2 ⋅ 3 = 6
  • 40 : 4 + 36 : 4 = 10 + 36 : 4 = 10 + 9 = 19
  • 12 : 4 + 24 : 3 = 3 + 24 : 3 = 3 + 8 = 11
  • 24 : 4 ⋅ 2 : 6 = 6 ⋅ 2 : 6 = 12 : 6 = 2
