Core: 3

Part 1- Choose #'s:

1) 0.7

2) -3

3) 6

4) -5/6

Part 2- Compare #'s:

1) 0.7 > -5/6

2) -3 < 6

3) -3 < 0.7

4) 6 > -5/6

5) 0.7 < 6

6) -5/6 > -3

Order from Least to Greatest:

-3, -5/6, 0.7, 6

Graph all four #'s on the number line:

Part 3- Absolute Value:

1) 6+|-5/6|= 6 5/6

2) |-3|+6= 9

3) |-3|+ 0.7= 3.7

4) 6+|0.7|= 6.7

Explanation: Absolute value is the distance a number is away from zero.

Part 4- Operations with Integers:

Addition:

1) -7 + -8= -15

2) -358 + 72= -286

Subtraction:

1) 72.9- 35.3= 37.6

2) -38-63= -101

Multiplication:

1) (-3 2/3)(-5 6/9)= 20 7/9

2) (7.77)(-68)= -528.36

Division:

1) 3 5/8 ÷ 2 1/8= 17/29

2) -9.6 ÷ 3.2= -3

Part 4- Real Life Word Problems:

1) Bobby had $5.93, earned $10.81 by cutting lawns, spent $7.18 on a candy bar and soda, and then earned $15.00 for baby-sitting. How much money does Bobby have?

$5.93+$10.81-$7.18+$15.00= $24.56 (Showed work on planning paper)

Answer: $24.56

2) Carly had $35.70, but she spent $43 on clothes at the mall. How much money does she need to buy a drink for $1.95?

$35.70-$43= -$7.30 $7.30+$1.25= $9.25 (Showed work on planning paper)

Answer: $9.25

3) Jay owed $6.38. Then he earned three times as much money as he owed. How much money does he have now?

($6.38)(3)= $19.14 $19.14-$6.38= $12.76

Answer: $12.76
