If \( \Large \sqrt{15} =3.88\),then what is the value of \( \Large \sqrt{\frac{5}{3}} \).

A) 1.29333....
B) 1.2934
C) 1.29
D) 1.295

Correct Answer:

A) 1.29333....

Description for Correct answer:
\( \Large \sqrt{\frac{5}{3}} \)

=\( \Large \sqrt{\frac{5 \times 3}{3 \times 3}} \)

=\( \Large \sqrt{\frac{15}{9}} =\frac{\sqrt{15}}{3}\)

=\( \Large \frac{3.88}{3} =1.29333....\)
