Irrational Numbers (4.2)

If the definition of a rational number is a number that can be written in the form m/n, where m and n are integers with n not equal to 0, what do you think an irrational number is? Text the number 37607, “865810” and then your answer. Bellwork

Irrational Numbers: A number that cannot be written in the form m/n, where m and n are integers with n not equal to 0.

Which are rational and which are irrational? 1) -3/5 2) The square root of 143) The cube root of 8/27 1)Rational, both are integers and written as a fraction. 2)Irrational, 14 does not have a perfect square root. 3)Rational, both 8 and 27 have perfect cube roots.
