Question

Please help me middle school Interpret dot plots with fraction operations

Answer 1

How generous of you to post the screenshot... sideways... xD. Next time try to post it so when we view it we can read it without rotating our laptops 90 degrees please. Anyways here's my answer/explanation.

The 5 smallest sodium chlorides are all 0.25 because there are 5 dots above the margin after 0, and there are 3 margins between 0 and 1, the first being "0.25", the second being "0.50" and the third being "0.75" in the line segment. If all of these have a mass of 0.25, then the "total mass" will be 0 because 0 + 0.25 + 0.25 + 0.25 + 0.25 is 0.25. Hope this helps. Found this helpful? Give it a Brainiest award if so.
