62 - 60.875 = 1.125
To find the range of a set of values, we need to calculate the difference between the highest and lowest values in the set. In this case, the closing prices of the common stock for the past week are given as:
61 1/2, 62, 61 1/4, 60 7/8, 61 1/2
To calculate the range, we need to find the highest and lowest values among these closing prices.
The highest value is 62, and the lowest value is 60 7/8.
To compare these two values, we can convert the fraction 7/8 to a decimal. To do that, we divide 7 by 8:
7 ÷ 8 = 0.875
Now we have the decimal value for 60 7/8, which is 60.875.
So, the highest value is 62, and the lowest value is 60.875.
To find the range, we subtract the lowest value from the highest value:
62 - 60.875 = 1.125
Therefore, the range of the closing prices of the common stock for the past week is $1.125.
Hence, the correct answer is option E: $1.125.
