Answer:

B. Is the correct way to show the problem.

Step-by-step explanation:

A: The number line is useless. It shows working backwards from the answer. You want to show how the answer was obtained. + goes right - goes left. Not A. This actually shows 1.1 - 0.8 - 0.3

C: C shows 0.8 - 0.3. Remember + goes right - goes left.

D: D is wrong. It shows 0.3 to 1.1 and then 0.3 back to 0.8. You are not doing that.

Error Analysis: Pedro compares 7/33 and 2/11. He incorrectly says 7/33 < 2/11 because 4.71 < 5.50. Compare 7/33 and 2/11.

madreJ [45]

He divided the wrong way. 7/33 = .2121.....and 2/11 = .1818...., so actually 2/11 < 7/33
