Question

Classify each number as rational or irrational.

-1/16
0
Square root of 3
Square root of 2

Answer 1

A number is rational if it can be expressed as the ratio between two integers (of course the denominator can't be zero).

-1/16 is already a fraction, so it's rational.

0 can be expressed as a fraction:
`(0)/(n)` for any non-zero integer
`n` you like

`√(2),√(3)` can't be expressed via a fraction between integers, and thus they are irrational.
