Use rational approximations of irrational numbers to compare the size of irrational numbers, locate them approximately on a number line diagram, and estimate the value of expressions (e.g., (2). For example, by truncating the decimal expansion of √2, show that √2 is between 1and 2, then between 1.4 and 1.5, and explain how to continue on to ...

17. True or False: If the number M is irrational, then 1/M must also be irrational. If you say "True," explain why the statement is true. If you say "False," give an example to show that the statement is false -- that is, give an example of a number M which is irrational but whose reciprocal 1/M is rational. 18.
