Answer 1

Пошаговое объяснение:

№6

15 : 3/5 = 15 * 5/3 = 75/3 = 25 (деревьев) - всего растет в саду

№7

1 1/14х = 1/7

15/14х = 1/7

х = 1/7 : 15/14

х = 1/7 * 14/15

х = 1/1 * 2/15

х = 2/15

х : 1/3 = 2,5

х = 2,5 * 1/3

х = 25/10 * 1/3

х = 25/30

х = 5/6

8 2/15 - (х + 3 5/14) : 5 5/8 = 7 1/3

(х + 3 5/14) : 5 5/8 = 8 2/15 - 7 1/3

(х + 3 5/14) : 5 5/8 = 7 17/15 - 7 5/15

(х + 3 5/14) : 5 5/8 = 12/15

х + 3 5/14 = 12/15 * 5 5/8

х + 3 5/14 = 4/5 * 45/8

х + 3 5/14 = 1/1 * 9/2

х + 3 5/14 = 9/2

х = 9/2 - 3 5/14

х = 4 1/2 - 3 5/14

х = 4 7/14 - 3 5/14

х = 1 2/14

х = 1 1/7
