I. Find the missing terms in the following sequences.
1) 2, 4, 8, 16, 32, 64
2) 1, 12, 23, 34, 45, 56
3) 8, 16, 24, 32, 40, 48
4) 80, 77, 74, 71, 68, 65
5) 50, 40, 32, 26, 22, 20
II. Find the missing number in each equation.
6) 4 x 8 = 8 x 4
7) (10 x 2) x 5 = 10 x (5 x 2)
8) 7 x (3 + 5) = (7 x 3 ) + (7 x 5)
9) 8 + 9 = 5 + 12
10) 5 x (6 + 2) = 5 x 8
III. Convert the following units as indicated.
11) 25000 sq. cm = 2.5 sq. m
12) 100000 sq. cm = 10 sq. m
13) 70000 sq. cm = 7 sq. m
14) 9 sq. m = 90000 sq. cm
15) 7.5 sq. m = 75000 sq. cm
IV. Solve the problem by answering the questions below.
16) What is asked? The perimeter of the rectangle.
17) What are the given? Shape of a rectangle that has a length of 20cm and width of 12 cm.
18) What operation to be used? Perimeter = 2L + 2W
19) What is the number sentence? P = 2(20) + 2(12)
20) What is the answer? Show the solution.
P = 2L + 2W
P = 2(20) + 2(12)
P = 40 + 24
P = 64cm
Ruben would need 64 cm of lace.
