Answer:

  N, Y, N, Y, Y, N, Y, N

Step-by-step explanation:

Rational: √121, 5/2, 58/3, -3.76, 0.37

Irrational: √20, √3, √14

__

The square root of a perfect square, such as √121 = √(11^2) = 11, is rational. The square root of any integer that is not a perfect square is irrational.

Any fraction or finite-length decimal number is rational. Any repeated decimal is also rational, regardless of the length of the repeat.
