Four students provide the following approximations for 0.89

89

Anyah states that

144 <

0.89 is between 0.44 and 0.45 because 044 <3

<045

Matthew states that 0.89 is between 0 and 1 because I <0.89 <1-

Rhoda states that 0.89 is between 0.9 and 1.0 because 0.92 <0.89 <1.02.

Ming states that 0.89 is between 0.93 and 0.95 because (0.93) 2 <089 < (0.95).

Which solution (s) are correct?

Anyah's only
