Should the number -7/8 be placed to the left or right of -1 on a number line?
Compare -0.875 to -1.00:
-0.875 is greater than -1 because it is closer to zero.
Since -0.875 is greater than -1, -7/8 should be placed to the right of -1 on a number line.
What is the median?

The scores of two classes test grades are recorded below. Which class performed better overall? How do you know?
Class A: 89, 87, 46, 99, 100, 98, 86, 52, 88, 82
Class B: 88, 89, 89, 39, 100, 100, 99, 86, 73, 84
Class B performed better overall, with a higher mean and median, even though they had a slightly wider range of scores. The higher average and middle score suggest more consistent strong performance, despite one low outlier (the 39).
