  • Answer 26 questions in 15 minutes.
  • If you are not ready to take this test, you can study here.
  • Match each statement with the correct term.
  • Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.
1. An equation with two ratios that are equal a/b = c/d






2. Line up the decimals then add or subtract normally






3. Out of 100






4. Number that is Not a part or fraction or decimal (1 - 2 - 15 - 382...)






5. Slide decimal 2 places to the left or /100






6. Top (numerator) / bottom (denominator) or find equivalent fraction over 10 - 100 - 1000






7. Number that is a part of a whole but divided into 10 or 100 or 1000 parts






8. Multiply normally then count the number of decimals & put that in your answer






9. Make all the same (same form and same length) then compare (all decimals easiest)






10. Put number over 10 - 100 - or 1000 (digits = zeros)






11. Numerator is larger than the denominator. Make mixed divide top/bottom- whole number and remainder is numerator - keep the denominator






12. Fraction with no common factors. Divide top & bottom by the same number until they have 2/8 = ¼






13. Decimal that goes on forever 5.5555... can round it 5.56 or 5.5 (line over 5 -or part that repeats) Cut off or truncated on a calculator 5.5555556






14. Number that doesn't end or repeat - must round ∏ = 3.14 or √2 = 1.41421356 rounded 1.4 Cut off or truncated on a calculator 3.14159265






15. 2 fractions with the same value ½ and 2/4. Multiply or divide top & bottom by the same number ie x 2






16. Decimal that ends 5.6






17. When the fraction is flipped 3/4 is 4/3 - used in dividing fractions






18. Decimal that is rounded in the calculator because the screen runs out of space






19. Comparison of numbers in a specific order (a:b or a to b or a/b)






20. Change percent to decimal then multiply






21. Part of a whole. Denominator - number on the bottom- how many parts the whole is divided into and Numerator - top part -how many you have






22. Type of rate when the bottom number is reduced to one(2 cookies per child 17km per 1 hour)






23. Number that has a Whole number and a fraction (1½) Make improper multiply denominator by whole & then add numerator






24. Slide the decimal straight up and then divide normally






25. Slide decimal 2 places to right or x100






26. Like a ratio but the numbers being compared are two different things (cookies per child or km per hour)
