Answer 1

15/27 сокращаем на 3=5/9
25/100 сокращаем на 25=1/4
20/600 сокращаем на 20=1/30
70/90 сокращаем на 10 =7/9

Answer 2

5\9 = 15 means that when you divide 5 by 9, the result is 15.

27 + 25\100 = 1\4 means that when you add 27 to 25 divided by 100, the result is 1 divided by 4.

1\30 = 20\600 means that 1 divided by 30 is equal to 20 divided by 600.

70\90 = 7\9 means that 70 divided by 90 is equal to 7 divided by 9.
