  1. 2. The dot that separates the whole number part from the fractional part of a decimal number.
  2. 4. A fraction where the numerator and denominator have no common factor other than 1.
  3. 6. One part out of one hundred equal parts; the second decimal place. Example — 0.07 = 7 hundredths.
  4. 7. A way to show part of a whole, written as a numerator over a denominator.
  5. 11. The top number in a fraction; tells how many parts are being considered.
  6. 13. The bottom number in a fraction; tells how many equal parts the whole is divided into.
  7. 16. The distance of a number from zero, always positive. Example — the absolute value of minus 6 = 6.
  8. 18. One part out of ten equal parts; the first place to the right of the decimal point. Example — 0.3 = 3 tenths.
  9. 19. One part out of one thousand equal parts; the third decimal place. Example — 0.004 = 4 thousandths.
  10. 20. A fraction where the numerator is less than the denominator; value is less than 1. Example — 3/4.
  11. 21. The largest number that divides evenly into two or more numbers; used to simplify fractions.
  12. 22. A number greater than zero.
  13. 27. A shared denominator used to compare, add or subtract fractions.

  1. 1. A number written as a whole number combined with a proper fraction. Example — 1 and 3/4.
  2. 3. A single number symbol from 0 to 9 used to form numbers.
  3. 5. Fractions that have different numerators and denominators but represent the same value. Example — 1/2 = 2/4 = 4/8.
  4. 8. A line with numbers placed at equal intervals in order, used to show the position and size of numbers including fractions and decimals.
  5. 9. Any number that can be written as a fraction a/b (where b is not zero), including integers, fractions, decimals and percentages.
  6. 10. The value of a digit depending on its position in a number. Each position is 10 times greater than the position to its right.
  7. 12. Any whole number, including negatives, zero and positives.
  8. 14. Arranging fractions from smallest to largest (or largest to smallest), usually by converting to a common denominator.
  9. 15. A fraction where the numerator is greater than or equal to the denominator; value is 1 or more. Example — 7/4.
  10. 17. The smallest common denominator shared by two or more fractions.
  11. 19. Cutting off digits after a certain decimal place without rounding.
  12. 23. Two numbers the same distance from zero on a number line but on opposite sides. Example — minus 4 and 4.
  13. 24. Finding an approximate answer, often using rounding, to check reasonableness.
  14. 25. A number less than zero, shown with a minus sign. Example — minus 5.
  15. 26. Replacing a number with a nearby value to a specified level of accuracy. If the next digit is 5 or more, round up; if less than 5, round down.
