ARational: negative 2 over 5, 1.5, 0 point 3 bar, square root of 9
Irrational: Square root of 7

Answer:

 Option A

Step-by-step explanation:

Given : terms = -2/5., square root of 7, 1.5, 0.333......, square root of 9.

To classify : Rational and irrational numbers

Rational numbers : It can be written as a fraction or a repeating digits to the right of the decimal point have end.

Irrational numbers: are those having endless non-repeating digits to the right of the decimal point.

We see term by term,

  • -2/5=-0.4 -- rational number
  • square root of 7 =2.645751311064590590501615753639260425710259183082450180368.. --irrational number
  • 1.5 = 3/2 --rational number
  • 0.3333...... -- rational number
  • square root of 9 = 3-- rational number

Therefore Option A is correct

Rational -negative 2 over 5., 1.5, 0 point 3 bar., square root of 9.

Irrational - square root of 7.
