# Fractions to decimals: will it recur?

In the previous step we asked you to practice converting random fractions into decimals. Did you spot any patterns?

## Explain

By considering the denominators of the fractions, how would you explain how we can tell whether a fraction will terminate or recur when expressed as a decimal?

We’ve included our explanation of how to determine whether a fraction terminates or recurs as a decimal in the final step of this week.

## Problem sheet

Now complete question 2 from this week’s worksheet.

## Teaching resource

For further ideas of how terminating and recurring decimals can be introduced in the classroom, watch this video from Teachers TV in which mathematics teacher Jonny Heeley inspires a group of students with an interactive lesson on decimals.

Terminating and recurring decimals are explored using a variety of games and challenges to excite and entertain. The students are also helped to calculate and use Pi.
