### Unit 15: Lesson 2

Interpret data on line plots

# Interpret line plots with fraction addition and subtraction

## Problem

During science class, groups measure out different volumes of vinegar. The line plot below shows the amount of vinegar used by 12 groups, rounded to the nearest start fraction, 1, divided by, 2, end fraction, start text, space, m, L, end text.
A line plot labeled 4 to 8 with tick marks every one-half unit labeled with a tick mark and number. Above tick mark four and one-half there is a column of two dots. Above tick mark 5 there is a column of three dots. Above tick mark six and one-half there is a column of two dots. Above tick mark 7, there is a column of two dots. Above tick mark seven and one-half, there is a column of three dots.
What is the total amount of vinegar, in milliliters, used by the 3 groups that used the most?
