We have the expression . To write a equivalent expression, we are going to rewrite the denominator of our expression using its common denominator 4:
Now, notice that we are basically diving 1 by , so we have a division involving fractions, and remember that to divide fractions, we just need to invert the second fraction and multiply:

We can conclude that the equivalent expression of is .

Draw a box plot for the data:<br> 135, 149, 156, 112, 134, 141, 154, 116, 134, 156

The box plot is attached.

We first order the data from least to greatest:
112, 116, 134, 134, 135, 141, 149, 154, 156, 156

We find the median (middle value). There are 10 data values, which puts the median between 135 and 141:
(135+141)/2 = 276/2 = 138

The Upper Quartile (UQ) is the median of the upper half of data, cut by the median. This is 154.

The Lower Quartile (LQ) is the median of the lower half of data, cut by the median. This is 134.

The middle line of the box is drawn at the median, 138. The left side of the box is at the LQ, 134. The right side of the box is at the UQ, 154. There is a whisker drawn from the right side to the highest value, 156. There is a whisker drawn from the left side to the smallest value, 112.
