Answer 1

Ответ:

1.  х = 10 17/36

5.  х = 2 39/46

6.  х = 9 2/3

Пошаговое объяснение:

1. х + 8 17/18 = 19 5/12

х + 161/18 = 233/12

х = 233/12 - 161/18

х = 699/36 - 322/36

х = 377/36

х = 10 17/36

5. 10 3/23 - х = 7 13/46

233/23 - х = 335/46

х = 233/23 - 335/46

х = 466/46 - 335/46

х = 131/46

х = 2 39/46

6. х - 3 1/5 = 6 7/15

х - 16/5 = 97/15

х = 97/15 + 16/5

х = 97/15 + 48/15

х = 145/15

х = 9 2/3
