Quarter Quiz 1 Review Sheet
On Monday, December 7, you will be given a quiz. To be prepared you are to review
the following.
Part 1 (Worth 20%)
Big Idea Questions to get ready with two examples.
1. When you simplify a numerical expression such as -05+8x4-(--4)+9.5 what
algorithm must you remember?
2. What is a difference between an algebraic expression and a numerical
expression?
3. When you are following the Order of Operations which comes first
multiplication or division?
4. How can I turn a fraction into a decimal using long division?
5. When you long divide to turn a fraction into a decimal what are the two types
of decimals that you will get as a result?
6. Extra Credit: How can you predict that the fraction will be terminating or
repeating by looking at the denominator? Give two examples.
Part 2 (Worth 80%) Show your Work.
Topic A: Converting Fraction to Decimals using Long Division
State Standard: 7.NS.d Convert a rational number to a decimal using long
division; know that the decimal form of a rational number terminates in 0s
or eventually repeats.

Topic B: Identify Terminating and Repeating Fractions (Rational Number)
without using long division.
State Standard: 7.NS.d Convert a rational number to a decimal using long
division; know that the decimal form of a rational number terminates in 0s
or eventually repeats.

BB.19 Write a repeating decimal as a fraction
Topic C: Simplify Numerical Expressions using Order of
Operations
State Standard: 7.NS.3 Solve real-world and mathematical problems
involving the four operations with rational numbers. (Computations with
rational numbers extend the rules for manipulating fractions to complex
fractions.)
