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






2. Slide decimal 2 places to right or x100






3. Line up the decimals then add or subtract normally






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






5. Decimal that ends 5.6






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






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






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






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






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






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






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






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






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






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






16. Change percent to decimal then multiply

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






19. 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






20. 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






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






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






23. Slide the decimal straight up and then divide normally






24. Out of 100






25. 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






26. An equation with two ratios that are equal a/b = c/d
