Question

Explain how you know that -3.4 is a rational number.

Answer 1

if the number terminates and is a real number it is rational, so what would you say from here?

Answer 2

terminates = the number ends or can be expressed as a fraction
9.333333 = 9 1/3 = 28/3 this is rational
pi = 3.14159265358979323846264338327950288... and can not be expressed into a fraction and does not end so this is irrational

Answer 3

I'm pretty sure -3.4 is rational.
Right?
