Answer 7

@aum

Answer 8

Choice D is still not clear to me.

Irrational number means the number cannot be put in the form m / n where m and n are integers.
A. 1/6. It is already put in the form m / n and so this is rational.
C. sqrt(49) = +7 or -7 which is a rational number.

Answer 10

@aum

Answer 11

B. sqrt(17). This cannot be put in the form integer / integer because 17 is not a perfect square.

D. 0.06 (It is zero point zero six. Not infinity!)
0.06 = 6 / 100. So 0.06 can be put in the form integer / integer. So this is rational.

So B is your answer.
