1)(3 1/3-1 2/3)×15 2)(5 2/5+9 1/6): 9 32/45 ​

Пошаговое объяснение:

1.

1) 3 1/3 - 1 2/3 = 10/3 - 5/3 = 5/3

2) 5/3 * 15 = 75/3 = 25

2.

1) 5 2/5 + 9 1/6 = 5 12/30 + 9 5/30 = 14 17/30

2) 14 17/30 : 9 32/45 =

437/30 * 45/437 = 45/30 = 1 15/30 = 1 1/2

1) 25,

2) 1 1/2.

Пошаговое объяснение:

1) (3 1/3 - 1 2/3) × 15 = 1 2/3 × 15 = 25

2) (5 2/5 + 9 1/6) : 9 32/45 = 14 17/30 : 9 32/45 = 437/30 : 437/45 =

= 437/30 × 45/437 = 19665/13110 = 3/2 = 1 1/2
