Question

Выполните действие:
-203*(-13)+1350:(-0,45) =
213,6:(-8,9)-(340)*0,25 =
-14/15*25/28+[-36/37]:[-6/37] =

Answer 1

Пошаговое объяснение:

№1

1) -203 * (-13) = 2639

2) 1350 : (-0,45) = -3000

3) 2639 + (-3000) = 2639 - 3000 = -361

№2

1) 213,6 : (-8,9) = -24

2) 340 * 0,25 = 85

3) -24 - 85 = -109

№3

1) -14/15 * 25/28 = -1/3 * 5/2 = -5/6

2) -36/37 : (-6/37) = -36/37 * (-37/6) = -6/1 * (-1/1) = 6/1 = 6

3) -5/6 + 6 = -5/6 + 5 6/6 = 5 1/6
