Пошаговое объяснение:

32.

А)

= (-2/7 * 3. 1/2) * (-2/3 * (-2. 1/4) ) =

(-2/7 * 7/2) * (-2/3 * (-9/4) ) = (-1/1 * 1/1) * (-1/1 * (-3/2) ) = -1 * 3/2 = -3/2 = -1. 1/2

Б)

= -6. 3/10 * 1/12 * (-1/7) *

8. 4/10 =

-63/10 * 1/12 * (-1/7) * 84/10 =

(-63/10 * (-1/7) ) * (1/12 * 84/10) =

(-9/10 * (-1/1) ) * (1/1 * 7/10) = 9/10 * 7/10 = 63/100

33.

1) 3. 1/3 - 2. 1/2 =

3. 2/6 - 2. 3/6 = 2. 8/6 - 2. 3/6 = 5/6

2) 5/6 * 2,4 = 5/6 * 2. 4/10 = 5/6 * 24/10 = 1/1 * 4/2 = 4/2 = 2

3) 15,5 + 4,5 = 20

4) 20 : 2. 1/2 = 20 : 5/2 = 20 * 2/5 = 40/5 = 8

5) 2 : 8 = 2/8 = 1/4
