Exam 1: Review of Real Numbers

Solve the problem. -If John puts $\frac { 3 } { 4 } \mathrm { lb }$ of roast beef on each sandwich, how many sandwiches can he make from $3 \frac { 3 } { 4 } \mathrm { lb }$ of roast beef?

Rewrite as a decimal. -0.7%

Simplify, where possible. -3(5a - 4)

Simplify. --20 - 5 + 12

Provide an appropriate response. -When a certain integer is added to -11 the result is

Simplify. - $7 + 2 ^ { 2 } - ( - 12 ) \cdot 11$

Simplify. -86 - 4 ∙ 5 + 153 ÷ (-9)

Simplify. - $\frac { 5 ( 2 + 1 ) - 6 ( 1 + 1 ) } { 5 ( 4 - 2 ) - 2 ^ { 3 } }$

Provide an appropriate response. -Rewrite the expression (10 ∙ m) ∙ n by applying the associative property. If the associative property does not apply, state this.

Simplify. - $- | 45 - 8 \cdot 3 | + 30 \div ( 5 - ( - 5 ) ) - 4 ^ { 2 }$

Simplify. - $\frac { 54 - 4 ( 17 - 13 ) } { ( 2 + 6 ) ^ { 2 } - 2 ( 37 - 6 ) }$

Simplify. - $\left( \frac { 3 } { 7 } + \frac { 3 } { 7 } \right) \cdot \frac { 7 } { 14 }$

Provide an appropriate response. -If a negative integer is divided by a positive integer, what can you say about the result?

Divide, if possible. --120 ÷ 0

Rewrite as a decimal. -0.022%

Subtract. Write your answer in lowest terms. - $\frac { 9 } { 21 } - \frac { 5 } { 21 }$

Identify whether the given number is a member of the following sets of numbers: A. natural numbers, B. whole numbers, C. integers, D. real numbers. -7.31

Choose the one alternative that best completes the statement or answers the question. -What is the additive inverse of 0?

Answer the question. -Is 8 a factor of 49,580?

Simplify. Your answer should be in lowest terms. - $14 - 7 \frac { 2 } { 3 }$
