Skip to 0 minutes and 7 seconds PAULA KELLY: Hello and welcome to the second week of our course, Exploring Fractions, Decimals, and Percentages.

Skip to 0 minutes and 13 seconds MICHAEL ANDERSON: Last week, we looked at why it is important to be clear about what the whole is when working with fractions, and that a fraction can be part of a whole, or a fraction can be part of many.

Skip to 0 minutes and 22 seconds PAULA KELLY: We also explored how to compare different fractions, create equivalent fractions, convert between mixed numbers and top-heavy fractions. You might want to take some time to look back over last week’s examples, the questions, and the other resources to consolidate your learning.

Skip to 0 minutes and 38 seconds MICHAEL ANDERSON: This week, we’ll look at fractions, decimals, and percentages in more detail. We’ll explore methods for converting between them, and introduce the idea of terminating and recurring decimals.

Skip to 0 minutes and 50 seconds PAULA KELLY: We’ll also explore a range of teaching strategies and tips to help our students to get to grips with the matter at hand.

Skip to 0 minutes and 57 seconds MICHAEL ANDERSON: As usual, this week will contain a mixture of videos, examples, and worked questions, and questions for you to have a go at yourself.

# Expressing fractions as decimals and as percentages

Last week we saw that it is essential that we consider what the ‘whole’ is when working with fractions, and that the whole can be made up of ‘one’ part or can be made up of ‘many’ parts. We compared the sizes of fractions, created equivalent fractions and expressed fractions as mixed numbers and top-heavy fractions.

This week we’ll look at fractions, decimals and percentages in more detail by exploring methods to convert between each of the different forms. You will also discover the difference between a terminating and a recurring decimal.

We explore a range of teaching strategies and tips to help students understand the differences and the similarities when expressing values in fractions, decimals and percentages.

As before, we’ll explore a range of teaching strategies and tips to help students understand the differences and the similarities when expressing values in fractions, decimals and percentages.

You can download this week’s accompanying worksheet of questions at the bottom of this first step.

The answers are provided on the final step of this week.
