Inequalities (A, B, D, and E) are correct.
Evaluate each inequality:
Which inequalities are correct.
A. 1.2 < (√5/2) < 1.8
(√5/2) is approximately 1.58, so, this is true.
B. (√3/2) < √2 < 1.5
(√3/2) is approximately 1.22 and √2 is approximately 1.41, so, this inequality is true.
C. 2.1 < 2.3 < √5
√5 is approximately 2.24, so, this is not true
D. √6 < 2.5 < √7
√6 is approximately 2.45 and √7 is approximately 2.65, so, this is true.
E. √3 < 1.8 < (√7/2)
√2 is approximately 1.73 and (√7/2) is approximately 1.87, so, this is true.
Therefore, inequalities (A, B, D, and E) are correct.
