Description

This interactive web-based resource allows students to convert decimals into fractions or fractions into decimals. To convert a fraction to a decimal, just divide the top number by the bottom number. The top number is called the numerator and the bottom number is called the denominator. You can do this either with a calculator or using long division.

Converting a terminating (non repeating) decimal to a fraction is a little harder. The first step is to multiply the decimal by a power of ten to move the decimal point all the way to the right. For example, if the decimal has three numbers behind the decimal place then you would multiply by a one with three zeros (1000). Now put that number over the power of 10 you multiplied by and reduce that fraction.

This activity can be used to:

  • convert fractions to decimals
  • convert decimals to fractions
  • develop number sense

 

Students can use the accompanying Exploration Questions to guide their investigations.
