Decimal Operations
The below QuickQuestion Interface © generates random decimal sums to do.
You can select a choice of one, two, or three decimal places for the questions, as well as choosing the mixed option, which will randomly set each number to a one of these choices.
You can then choose whether the numbers will be purely decimals, have an integer part to them or be one of each.
Finally, select the operation you wish to use.
If you wish to make the activity slightly easier (particularly for multiplcation and division), then by selecting the checkbox you can ensure that one of the numbers is always a whole number.
Now use the "New Question" and "Show Answer" buttons to generate questions and answers.
All answers are given to 6 decimal places.
There is a 10QQI version of this activity which generates 10 random questions at a time.
