Answer 1

Пошаговое объяснение:

а)

42/98 = (42:2)/(98:2) = 21/49 => (21:7)/(49:7) = 3/7

24/56 = (24:2)/(56:2) = 12/28 => (12:4)/(28:4) = 3/7

18/81 = (18:3)/(81:3) = 6/27 => (6:3)/(27:3) = 2/9

6/20 = (6:2)/(20:2) = 3/10

60/156 = (60:2)/(156:2) => 30/78 => (30:2)/(78:2) = 15/39 => (15:3)/(39:3) = 5/13

150/400 = (150:5)/(400:5) = 30/80 => (30:2)/(80:2) = 15/40 => (15:5)/(40:5) = 3/8

б)

5/10 = (5:5)/(10:5) = 1/2

14/63 = (14:7)/(63:7) = 2/9

8/32 = (8:8)/(32:8) = 1/4

25/40 = (25:5)/(40:5) = 5/8
