Explicație pas cu pas:
a) 2 1/7 = (2·7+1)/7 = 15/7 ≈ 2,1 =>
2 < 2 1/7 < 3
b) -3 2/5 = (-3·5+2)/5 = -13/5 = -6,5
-7 < - 3 2/5 < -6
c) 101,(02) =>
101 < 101,(02) < 102
d) -13,14 =>
-14 < -13,14 < -13
e) 707/31 ≈ 22,8 =>
22 < 707/31 < 23
f) - (6³+6²+6¹+6⁰)/36 = - (216+36+6+1)/36 = - 259/36 = - 7,19(4)
-8 < -(6³+6²+6¹+6⁰)/36 < -7
