Answer 1

Пошаговое объяснение:

1)

1 5/9 * 0,375 - 1 2/7 : 3 3/7 + 0,9 * 25/27 =

14/9 * 375/1000 - 9/7 : 24/7 + 9/10 * 25/27 =

14/9 * 3/8 - 9/7 * 7/24 + 9/10 * 25/27 =

7/3 * 1/4 - 3/1 * 1/8 + 1/2 * 5/3 =

7/12 - 3/8 + 5/6 = 14/24 - 9/24 + 20/24 =

(14-9+20)/24 = 25/24 = 1 1/24

2)

9/16 : 3,375 + 1 1/25 * 1 2/3 - 1/35 * 24,5 =

9/16 : 3 375/1000 + 1 1/25 * 1 2/3 - 1/35 * 24 5/10 =

9/16 : 27/8 + 1 1/25 * 1 2/3 - 1/35 * 24 1/2 =

9/16 * 8/27 + 26/25 * 5/3 - 1/35 * 49/2 =

1/2 * 1/3 + 26/5 * 1/3 - 1/5 * 7/2 =

1/6 + 26/15 - 7/10 = 5/30 + 52/30 - 21/30 =

(5+52-21)/30 = 36/30 = 6/5 = 1 1/5
