i am taking a job related test with many math sections. I am long out of school and need some tutorials as well as practice questions and answers. The topics are as follows:
-multiplication and division of fractions and mixed numbers
-calculating percentages
-calculating ratios and proportions
-basic rules of probability
-calculating rate using distance and time
-calculating work related problems
-calculating averages
-solving for unknown quantities
-expressing word problems as equations
-calculating the area of an object
i am looking for basic tutorials on how to answer questions of this nature using different methods. If anyone knows of any tricks that would also be very helpful. Any help would be greatly appreciated.
