Unit 6

4. the part of a fraction written above the fraction bar that tells the number of fractional parts specified or being considered
7. the rules of which calculations are performed first when simplifying and expression
8. a number in the form a/b where a and b are whole numbers and b is not equal to zero. A fraction can be used to name part of an object, part of a set of objects, to compare two quantities, or to represent division.
9. a number that is composed of a whole number and a fraction
10. the part of a fraction written below the fraction bar that tells the total number of equal parts in a whole or set
12. if three or more addends are added, they can be grouped in any order, and the sum will remain the same; a + b + c = (a + b) + c = a + (b + c)
13. symbols to show a group of terms and/or expressions within a mathematical expression

1. if the order of the addends are changed, the sum will remain the same; a + b = c; therefore, b + a = c
2. the least common multiple of the denominators of two or more fractions
3. a mathematical phrase, with no equal sign or comparison symbol, that may contain a number(s), an unknown(s), and/or and operator(s)
5. a number in the form a/b where a and b are whole numbers and a > b where b is not equal to zero
6. a number in the form a/b where a and b are whole numbers and a < b where b is not equal to zero
11. a fraction in the form 1/b representing the quantity formed by one part of a whole that has been partitioned into b equal parts where b is a non-zero whole number
