Dana Dutch Math 115- Week 8 Checkpoint Section 9.1 16. Convert to a common bottom (14): 6/14, -12/14, 2/14, -7/14, 4/14 Now order them by their tops: -12/14, -7/14, 2/14, 4/14, 6/14 Back to the way they were in the problem: -6/7, -1/2, 1/7, 2/7, 3/7 32. |4| + |-3| = 4 + 3 = 7 44. |-9| - |-4| = 9 - 4 = 5 Section 9.2 40. = 7 – 9 – 5 + 6 = -2 – 5 + 6 = -7 + 6 = -1 48. = 1/3 – 5/6 – ½
