# Line Plots with Fractions - Grade 4 Math Worksheet
Section A: Multiple Choice Questions
Q1: A line plot shows the lengths of pencils in inches: \(\frac{1}{4}\), \(\frac{1}{2}\), \(\frac{1}{4}\), \(\frac{3}{4}\), \(\frac{1}{2}\), \(\frac{1}{4}\). How many pencils are \(\frac{1}{4}\) inch long? (a) 1 (b) 2 (c) 3 (d) 4
Solution:
Ans: (c) Explanation: Count the number of times \(\frac{1}{4}\) appears in the data: \(\frac{1}{4}\), \(\frac{1}{4}\), and \(\frac{1}{4}\). There are 3 pencils that are \(\frac{1}{4}\) inch long.
Q2: On a line plot, each X represents one data point. If there are 4 X's above \(\frac{1}{2}\), what does this tell you? (a) The value \(\frac{1}{2}\) appears 4 times in the data (b) There are 4 different measurements (c) The total of all data is 4 (d) The value \(\frac{1}{2}\) is the largest
Solution:
Ans: (a) Explanation: Each X on a line plot represents one occurrence of that value. If there are 4 X's above \(\frac{1}{2}\), it means \(\frac{1}{2}\) appears 4 times in the data set.
Q3: A line plot shows amounts of water in cups: \(\frac{1}{4}\), \(\frac{2}{4}\), \(\frac{3}{4}\), \(\frac{2}{4}\), \(\frac{1}{4}\). Which measurement appears most often? (a) \(\frac{3}{4}\) (b) \(\frac{2}{4}\) (c) \(\frac{1}{4}\) (d) They all appear equally
Solution:
Ans: (d) Explanation: Count each measurement: \(\frac{1}{4}\) appears 2 times, \(\frac{2}{4}\) appears 2 times, and \(\frac{3}{4}\) appears 1 time. Since \(\frac{1}{4}\) and \(\frac{2}{4}\) both appear twice, we need to reconsider. Actually, \(\frac{1}{4}\) and \(\frac{2}{4}\) each appear 2 times, making them tied for most frequent. However, reviewing the options and data more carefully: \(\frac{1}{4}\) and \(\frac{2}{4}\) both appear the same number of times (2 each), so no single measurement appears most often - but option (d) states they all appear equally, which is incorrect. Let me recount: \(\frac{1}{4}\) appears twice, \(\frac{2}{4}\) appears twice, \(\frac{3}{4}\) appears once. Both \(\frac{1}{4}\) and \(\frac{2}{4}\) are tied. Given the options, both (b) and (c) appear equally most often (2 times each). The best answer considering typical Grade 4 questions would be either (b) or (c), but since they're equal, the question needs adjustment.
Q3: A line plot shows amounts of water in cups: \(\frac{1}{4}\), \(\frac{2}{4}\), \(\frac{3}{4}\), \(\frac{2}{4}\), \(\frac{2}{4}\). Which measurement appears most often? (a) \(\frac{3}{4}\) (b) \(\frac{2}{4}\) (c) \(\frac{1}{4}\) (d) All measurements appear equally
Solution:
Ans: (b) Explanation: Count each measurement: \(\frac{1}{4}\) appears 1 time, \(\frac{2}{4}\) appears 3 times, and \(\frac{3}{4}\) appears 1 time. The measurement \(\frac{2}{4}\) appears most often with 3 occurrences.
Q4: What is the difference between the largest and smallest values on this line plot: \(\frac{1}{8}\), \(\frac{3}{8}\), \(\frac{5}{8}\), \(\frac{7}{8}\)? (a) \(\frac{4}{8}\) (b) \(\frac{5}{8}\) (c) \(\frac{6}{8}\) (d) \(\frac{8}{8}\)
Solution:
Ans: (c) Explanation: The largest value is \(\frac{7}{8}\) and the smallest value is \(\frac{1}{8}\). To find the difference: \(\frac{7}{8} - \frac{1}{8} = \frac{6}{8}\).
Q5: A line plot uses a number line marked in fourths. Which fraction would NOT appear on this line plot? (a) \(\frac{2}{4}\) (b) \(\frac{3}{4}\) (c) \(\frac{2}{8}\) (d) \(\frac{1}{4}\)
Solution:
Ans: (c) Explanation: A line plot marked in fourths shows fractions with denominator 4, such as \(\frac{1}{4}\), \(\frac{2}{4}\), \(\frac{3}{4}\), and \(\frac{4}{4}\). The fraction \(\frac{2}{8}\) has a different denominator (8) and would not typically appear on a number line marked in fourths, unless converted to \(\frac{1}{4}\).
Q6: How many total data points are shown on a line plot if there are 3 X's above \(\frac{1}{4}\), 2 X's above \(\frac{2}{4}\), and 1 X above \(\frac{3}{4}\)? (a) 3 (b) 4 (c) 6 (d) 7
Solution:
Ans: (c) Explanation: To find the total number of data points, add all the X's together: 3 + 2 + 1 = 6. There are 6 total data points on the line plot.
Q7: Students measured ribbon lengths in feet: \(\frac{2}{8}\), \(\frac{4}{8}\), \(\frac{6}{8}\), \(\frac{4}{8}\). On a line plot, how many X's would be above \(\frac{4}{8}\)? (a) 1 (b) 2 (c) 3 (d) 4
Solution:
Ans: (b) Explanation: Count how many times \(\frac{4}{8}\) appears in the data: \(\frac{4}{8}\) appears twice. Therefore, there would be 2 X's above \(\frac{4}{8}\) on the line plot.
Q8: Which fraction is equivalent to \(\frac{2}{4}\) and could be used to represent the same point on a line plot? (a) \(\frac{1}{2}\) (b) \(\frac{2}{8}\) (c) \(\frac{3}{4}\) (d) \(\frac{1}{4}\)
Solution:
Ans: (a) Explanation:Equivalent fractions represent the same value. \(\frac{2}{4} = \frac{1}{2}\) because when you simplify \(\frac{2}{4}\) by dividing both numerator and denominator by 2, you get \(\frac{1}{2}\). These fractions would represent the same point on a number line.
Section B: Fill in the Blanks
Q9: A __________ is a graph that uses X's or dots above a number line to show data.
Solution:
Ans: line plot Explanation: A line plot is a type of graph that displays data using marks (X's or dots) above a number line to show frequency of values.
Q10: On a line plot, each X represents one __________ in the data set.
Solution:
Ans: data point (or value or measurement) Explanation: Each X on a line plot represents one data point, which is a single measurement or value collected in the data set.
Q11: If a line plot is marked in eighths, the fractions would have a denominator of __________.
Solution:
Ans: 8 Explanation: When a number line is marked in eighths, it is divided into 8 equal parts, so all fractions shown have a denominator of 8, such as \(\frac{1}{8}\), \(\frac{2}{8}\), \(\frac{3}{8}\), etc.
Q12: The value that appears most often in a data set is called the __________.
Solution:
Ans: mode Explanation: The mode is the value that occurs most frequently in a data set. On a line plot, the mode is the value with the most X's above it.
Q13: To find how many data points are in a line plot, you __________ all the X's.
Solution:
Ans: count (or add) Explanation: To find the total number of data points, you count or add all the X's shown on the line plot.
Q14: The fractions \(\frac{1}{2}\) and \(\frac{2}{4}\) are __________ fractions because they represent the same amount.
Solution:
Ans: equivalent Explanation:Equivalent fractions are fractions that have the same value even though they may look different. \(\frac{1}{2}\) and \(\frac{2}{4}\) both represent one-half.

Solution:
Ans: Step 1: Count each measurement Step 2: \(\frac{1}{8}\) appears 2 times, \(\frac{3}{8}\) appears 3 times, \(\frac{5}{8}\) appears 1 time Step 3: \(\frac{3}{8}\) appears most often Final Answer: \(\frac{3}{8}\) inch appears most often; it appears 3 times

Solution:
Ans: Step 1: Add all the X's to find total data points Step 2: 4 + 3 + 2 = 9 Final Answer: 9 erasers were measured in total
Q18: Students measured string lengths in feet: \(\frac{1}{4}\), \(\frac{2}{4}\), \(\frac{3}{4}\), \(\frac{2}{4}\), \(\frac{1}{4}\), \(\frac{3}{4}\), \(\frac{2}{4}\). What is the difference between the longest and shortest string?

Solution:
Ans: Step 1: Count how many times \(\frac{4}{8}\) appears in the data Step 2: \(\frac{4}{8}\) appears 3 times Step 3: Simplify \(\frac{4}{8}\): \(\frac{4}{8} = \frac{1}{2}\) Final Answer: There will be 3 X's above \(\frac{4}{8}\); another name for \(\frac{4}{8}\) is \(\frac{1}{2}\)
Q20: Emma recorded how far she walked each day in miles: \(\frac{1}{4}\), \(\frac{2}{4}\), \(\frac{1}{4}\), \(\frac{3}{4}\), \(\frac{2}{4}\), \(\frac{1}{4}\), \(\frac{2}{4}\). On a line plot, which distance would have the most X's above it?
Solution:
Ans: Step 1: Count each distance Step 2: \(\frac{1}{4}\) appears 3 times, \(\frac{2}{4}\) appears 3 times, \(\frac{3}{4}\) appears 1 time Step 3: Both \(\frac{1}{4}\) and \(\frac{2}{4}\) appear most often with 3 X's each Final Answer: Both \(\frac{1}{4}\) mile and \(\frac{2}{4}\) mile would have the most X's (3 X's each)
