Răspuns:
e) x = {28, 29, 30, 31, 32, 33, 34, 35}
f) x = {26, 27, 28}
Explicație pas cu pas:
e)
7/9 ≤ x/36 < 5/6
( aducem fractiile la acelasi numitor )
28/36 ≤ x/36 < 30/36
28 ≤ x < 36
x = {28, 29, 30, 31, 32, 33, 34, 35}
f)
25% < x/100 < 29%
25% = 25/100
29% = 29/100
25/100 < x/100 < 29/100
25 < x < 29
x = {26, 27, 28}
