Round each decimal to the
place value indicated.
7.569 to the nearest tenth
7.569 to the nearest hundredth
7.569 to the nearest one
$300
Remember that the place after the place
you’re rounding to determines whether
you round up or not.
7.569 to the nearest tenth is 7.6
7.569 to the nearest hundredth is 7.57
7.569 to the nearest one is 8
$300
Convert the following.
2 quarts = ____ pints
1 meter = ____ centimeters
1 yard = ____ feet
$300
1 quarts = 2 pints
1 qt = 2 pints, so multiply 1 by 2
1 meter = 100 centimeters
1 m = 100 cm, so multiply 100 by 1
1 yard = 3 feet
1 yd. = 3 ft., so multiply 1 by 3

You add all the green eggs.
80 + 60 + 50 + 30 = 160 green
eggs.
$300
Add
1/4 + 2/3 + 1/6 = n
$400
1/4 + 2/3 + 1/6
1/4 = 3/12
2/3 = 8/12
1/6 = 2/12
3/12 + 8/12 + 2/12 =
13/12 =
1 1/12

The length of each side of the
rectangle is 8 in. and the width
is 7in. Find the perimeter and
area.
$400
The perimeter is the distance around
the sides of a shape so it is
8 + 8 + 7 + 7 or
8
(8 + 7) X 2 = 30 in.
7
The area of a rectangle is
length x width so it is
8 x 7 = 56 in.²
$400
How many lines of symmetry does a
rectangle have?
How many lines of symmetry does a

Karen is putting a blue ribbon around
the outside edge of a 6 inch by 7 inch
rectangular note. How much ribbon
does she need?
Karen then decides to put a
rectangular piece of gold paper in the
middle of the rectangle. How many
square inches does she need?
$500
The ribbon has to be 24 inches long.
Formula for perimeter (L + W) X 2,
So 6 + 7 + 13 and 13 x 2 = 26 inches.
The gold paper had to be 35 inches2.
Area = ( L X W)
So 6 X 7 = 42 inches2.
L = length
$500
W = width
