Dividing integers

Dividing integers

In this section, we will keep working on dividing integers. We will learn how to read and represent division statements on a number line. We will then practice more integer divisions with actual numbers and word problems.
Basic concepts: Multiplying integers, Understanding integer division,
Related concepts: Multiplying and dividing monomials , Solving linear equations using multiplication and division, Solving one-step linear inequalities,

Lessons

In this lesson, we will learn:

  • Understanding Division Using a Number Line
  • Solving Division Statements Using a Number Line
  • Division Statements With Integer Quotients

Notes:
  • Recurring/ repeating decimals: decimal numbers whose digits repeat forever.
  • For the recurring decimals, we put either a bar or dots above the recurring parts.
