Lesson 1: Topic A: Foundations

# Reading a line plot with fractions

Explore the concept of interpreting data on line plots, particularly focusing on how to read and understand line plots that display measurements in fractions. Understand the importance of comparing data points and calculating differences between them. Created by Sal Khan.

• Why are there sometimes extra dots on some parts of the line plot?
• If a number has more than one dot above it, that means that particular measurement was recorded more than one time. In the video, it shows two dots above the 10.5 mark. This means that out of the 13 cities that the researchers took measurements from, two of them had an average monthly rainfall of 10.5 inches.
• At , I don't get why you have to subtract the different fractions.
• This is basic. We were supposed to find the difference between the two numbers, in this case the two rainiest cities. So we subtract. Like if we were to find the total we add but if we were to find the difference we subtract.
• why did khan - 13 and 1/2 -13 and 1/4 it dosent make any sense
• Im pretty sure because the rainiest city is 13 2/4 but Sal just simplified it, so 13 1/2
• Can you make another video please? I stil don't understand this. (Open for help)
• It was not realy understandable but it was kind of helpfull but ya.
• Yeah.... I'm learning this (a little) for 5'th grade next year.🤔 I'm so confused
• i don't get how it says measurements are rounded to 1/4
• Why are there sometimes extra dots on some parts of the line plot?
