The Fractions Interaction is not one of the Portable Custom Interactions in the standard TAO package. It will need to be installed in a separate extension.
The Fractions interaction is useful if you wish to set a test question where you ask the Test-taker to express a fraction of something visually. Test-takers can do this by first defining the denominator and then highlighting the correct number as the numerator.
If you wish to use the Fractions interaction, the corresponding extension will need to be installed first. See the chapter on the Extensions Manager for information on how to do this, or ask your systems administrator about the installation of this extension.
This interaction supports automatic scoring.
