Place the numbers in ascending order. 

1 and 1/5,   -2 and 1/8,   0.7,   -9/5,   -0.75,   5/3

-2 1/8, -9/5, -0.75, 0.7, 1 1/5, 5/3

Put in order from least to greatest. 0.35, 30%, - 33%

What is - 33%, 30%, 0.35 negative first, 30% = 0.30, then 0.35

Which statement is true and why?

a) 2.6 x 10^-2 = -0.026 

b) 3 x 10^3 < 3000  

c) 83,000 = 8.3 x 10^4

c is correct because they equal in standard form b is wrong (they equal) a is wrong (there is no negative in front of standard form)

200

List the numbers from greatest to least. 

-0.2 inch, 1/5 inch, 0.03 inch, 1/3 inch, -3/8 inch

Tanner and Kelsee need to write 2,400,000 using scientific notation. 

Tanner claims that 2,400,000 = 2.4 x 10^5 and Kelsee claims that 2,400,000 = 2.4 x 10^6. 

Who is correct and WHY?

Kelsee is correct because the decimal goes between the 2 and 4, and the original decimal point in the standard form moves to the left 6 places. (Tanner is wrong because he counted zeros.)

Fill in the blanks with < , >, or = 

-3 x 10^2   ____    3 x 10^-2

-3 x 10^2   <   3 x 10^-2

-3 x 10^2 is smaller (-300 is smaller than 0.03), but if it was a positive 3 instead it would be greater. Negatives are smaller than all positives

500

Write the following numbers in scientific notation with the proper sign (less than or greater than) between the numbers to make a true statement. 

0.0001663 and 0.0000837

1.663 x 10^-4 > 8.37 x 10^-5 

or 8.37 x 10^-5 < 1.663 x 10^-4
