Official Solution:

The sum \(1.4 + \frac{1}{7}\) is between

A. 1.40 and 1.45
B. 1.45 and 1.50
C. 1.50 and 1.55
D. 1.55 and 1.60
E. 1.60 and 1.65

\(1.4 + \frac{1}{7} \gt 1.4 + \frac{1}{10} = 1.5\); \(1.4 + \frac{1}{7} \lt 1.4 + \frac{3}{20} = 1.4 + 0.15 = 1.55\).

Answer: C

Your answer is incorrect.

1/7= 0.1428. Therefore, 1.4+0.1428=1.5428

There can be some number between 1.5428 and 1.55. Correct answer should be B.

1.54 IS between 1.50 and 1.55. The answer is correct.

P.S. ALL answers on the tests are correct.
