Answer 1

Пошаговое объяснение:

5)

3 3/7 / |-7 3/7| = у/13

3 3/7 / 7 3/7 = у/13

7 3/7 * у = 3 3/7 * 13

52/7у = 24/7 * 13

52/7у = 312/7

у = 312/7 : 52/7

у = 312/7 * 7/52

у = 6/1 * 1/1

у = 6/1

у = 6

6)

9/у = |-4 1/11| / |-7 3/11|

9/у = 4 1/11 / 7 3/11

4 1/11 * у = 7 3/11 * 9

45/11у = 80/11 * 9

45/11у = 720/11

у = 720/11 : 45/11

у = 720/11 * 11/45

у = 16/1 * 1/1

у = 16/1

у = 16

7)

|-23|/у = |-3 37/49| / 4 4/49

23/у = 3 37/49 / 4 4/49

3 37/49 * у = 4 4/49 * 23

184/49у = 200/49 * 23

184/49у = 4600/49

у = 4600/49 : 184/49

у = 4600/49 * 49/184

у = 25/1 * 1/1

у = 25/1

у = 25
