You Did Less Than 1/5 - That's a FAIL
Unfortunately, you got 1/5 or less of the answers right. That means you have a lot of work to do with fractions, starting with basics and moving on to multiplication and division of fractions. Many online sites offer free lessons and worksheets for practicing. Don't let your math go to waste.
You Got Around a 4/15 to 7/15 of the answers right: Not Great
While not a complete fail, this was not a strong score. This means you may have the basics of fractions right but perhaps are out of practice using them in multiplication, finding a shared number, and fraction division. Many online sites offer free worksheets for practicing your basics again and getting a firmer hand on this old material you probably haven't had to use in a while.
You Did Between 7/15 and 3/4 - That's Good!
You definitely know your way around fractions, and it's hard to stump you. That said, it could be some time since you practiced, so some questions did get by you. We're sure you've got the basics down pat so if you try again we have little doubt you can ace this test completely. Why not try again since you surely know this material? If not, maybe have a quick look at your mistakes below to know where you went wrong.
4/5 to 5/5 - You ACED IT!
Wow, you got over 75% in the test, perhaps even aced it completely! Way to go, you truly know your fractions, and it's almost impossible to throw YOU for a loop no matter how hard the fractions or how incompatible they may seem to be. You have that mathematical eye that finds the shared rules for those fractions and with it the answer. You rock the fractions!
