6. Relationship in which a number is smaller than another






7. Dividing fractions






8. The bottom number in a fraction; tells how many parts a whole is divided into OR how many parts in a group - E.g. 2/4 and what position is the 4?






9. A number that is multiplied by another number to find a producr






10. A comparison of 2 numbers; one form is a fraction






11. Reducing fractions

13. Rational numbers in decimal form that have a block of on or more digits that repeat continuously






14. Rational numbers that expressed in decimal format that have fixed number of digits. 1.5 etc.






15. A number written in expanded form with the place values written in exponential form - E.g. 2432=2000+400+30+2






16. The value of a digit based on its position within a number - e.g. 2 -432 The position of the numbers






17. Two factors together that are multiplied to equal a larger number.
