Key Concepts of Chapter 1 Exercise 1.2

• Representation on Number Line: To represent a rational number a/b, we divide the distance between two consecutive integers into b equal parts.
• Rational Numbers between two Rational Numbers: There are countless (infinite) rational numbers between any two given rational numbers.
• The Mean Method: One way to find a rational number between a and b is to find their average: (a+b)/2.
• The Common Denominator Method: A faster way to find multiple rational numbers by making the denominators the same and then expanding the numerators.
