For the following numbers, which is the correct order of the variables from smallest to largest? P = 0.004 Q = 0.04 R = - 40 S = -0.4 T = ¹⁄₄

To solve these questions, you need to put the numbers in increasing order. This will allow you to easily compare which numbers are larger or smaller. One strategy is to convert fractions to decimals to compare. Remember, when putting them in order that the placement of the numbers (1, 10, 0.1, 0.01) is crucial. Also remember that negative numbers mirror the positive ones (-10 is smaller than -5 for example) For this set:
First convert the fractions to decimals:
T=¼ =0.25
Then place them in order from least to greatest (like you would see on a number line):
-40           -0.4            0.004           0.04        0.25
R               S                  P                Q             T
