Answer 1

Ответ:

Пошаговое объяснение:

N 1

1) 45/80 = (45:5)/(80:5) =

9/16

2) 324/405 = (324:81)/(405:81) = 4/5

N 2

1) 3/4 и 2/5 =

(3*5)/(4*5) и (2*4)/(5*4) =

15/20 и 8/20

2) 17/20 и 1/2 =

17/20 и (1*10)/(2*10) =

17/20 и 10/20

N 3

1) 1/3 и 17/60 =

(1*20)/(3*20) и 17/60 =

20/60 и 17/60.

20/60 > 17/60, значит:

1/3 > 17/60

2) 4/7 и 8/3 =

(4*3)/(7*3) и (8*7)/(3*7) =

12/21 и 56/21

12/21 < 56/21, значит:

4/7 < 8/3
