- 2. The dot that separates the whole number part from the fractional part of a decimal number.
- 4. A fraction where the numerator and denominator have no common factor other than 1.
- 6. One part out of one hundred equal parts; the second decimal place. Example — 0.07 = 7 hundredths.
- 7. A way to show part of a whole, written as a numerator over a denominator.
- 11. The top number in a fraction; tells how many parts are being considered.
- 13. The bottom number in a fraction; tells how many equal parts the whole is divided into.
- 16. The distance of a number from zero, always positive. Example — the absolute value of minus 6 = 6.
- 18. One part out of ten equal parts; the first place to the right of the decimal point. Example — 0.3 = 3 tenths.
- 19. One part out of one thousand equal parts; the third decimal place. Example — 0.004 = 4 thousandths.
- 20. A fraction where the numerator is less than the denominator; value is less than 1. Example — 3/4.
- 21. The largest number that divides evenly into two or more numbers; used to simplify fractions.
- 22. A number greater than zero.
- 27. A shared denominator used to compare, add or subtract fractions.
Down
- 1. A number written as a whole number combined with a proper fraction. Example — 1 and 3/4.
- 3. A single number symbol from 0 to 9 used to form numbers.
- 5. Fractions that have different numerators and denominators but represent the same value. Example — 1/2 = 2/4 = 4/8.
- 8. A line with numbers placed at equal intervals in order, used to show the position and size of numbers including fractions and decimals.
- 9. Any number that can be written as a fraction a/b (where b is not zero), including integers, fractions, decimals and percentages.
- 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.
- 12. Any whole number, including negatives, zero and positives.
- 14. Arranging fractions from smallest to largest (or largest to smallest), usually by converting to a common denominator.
- 15. A fraction where the numerator is greater than or equal to the denominator; value is 1 or more. Example — 7/4.
- 17. The smallest common denominator shared by two or more fractions.
- 19. Cutting off digits after a certain decimal place without rounding.
- 23. Two numbers the same distance from zero on a number line but on opposite sides. Example — minus 4 and 4.
- 24. Finding an approximate answer, often using rounding, to check reasonableness.
- 25. A number less than zero, shown with a minus sign. Example — minus 5.
- 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.
