Lesson 4-1 Rational Numbers.
T-Take the challenge! Write the CQ in jour journal below
the title: Challenge Question: What is the difference
between whole numbers, integers and rational numbers?
Can a number be more than one of these?
Take a minute to think about the CQ and write your answer
in your journal.

False. All integers are rational numbers, but some rational numbers are not
integers. For example: 0.75 is a rational number because it can be expressed
as the ratio 3
