Question

помогите срочно нужно только 2 4 6 пункт пожалуйста ​

Answer 1

Пошаговое объяснение:

5,1(5) = 5 (15 - 1)/90 = 15 14/90 = 5 7/45

1,(18) = 1 (18 - 0)/99 = 1 18/99 = 1 2/11

1,3(6) = 1 (36 - 3)/90 = 1 33/90 = 1 11/30

5,(432) = 5 (432 - 0)/999 = 5 432/999 = 5 16/37

11,(243) = 11 (243 - 0)/999 = 11 243/999 = 11 9/37

№2

5,1(5) - 1,(18) = 5 7/45 - 1 2/11 = 5 77/495 - 1 90/495 = 4 572/495 - 1 90/495 = 3 482/495 = 3 97/99

№3

18 : 1,3(6) = 18 : 1 11/30 = 18 : 41/30 = 18 * 30/41 = 540/41 = 13 7/41

№4

5,(432) + 11,(243) = 5 16/37 + 11 9/37 = 16 25/37
