Once at the IXL site and you can move your mouse over any skill name to view a sample question for familiarization and recognition.
Familiarize yourself with each question by determining what is asked and what is given. Ask and answer How are questions similar and different?
Then attempt to answer each question by recognizing it, determine the rules needed fr a solution, find the solution y applying the rules and then checking to see if this is all correct.
Then practice getting answers to the questions by fluently applying the rules. Just click on any skill link. IXL will then time your session and track your score. The questions will automatically increase in difficulty as you improve!
FINALLY, master application of the Fraction Rule Set for all skills at this Link.
