Printable math worksheet for students to create a bar graph based on book reading data.

I will solve the problem step by step based on the information provided in the image.

Step 1: Analyze the Data

First, I need to extract the data for each person from the image. The table shows the number of pages read by each individual:
- Adam: 40 pages
- Maria: 24 pages
- Scott: 64 pages
- Frank: 32 pages
- Linda: 56 pages

This data will be used to answer all four questions.

Step 2: Answer Question 1

Question 1: What unit of scale is used to display the number of pages read?

Looking at the vertical axis (Y-axis) of the bar graph, it is labeled "Number of pages" and has markings from 0 to 80. The increments are in steps of 8 (0, 8, 16, 24, 32, 40, 48, 56, 64, 72, 80).

The unit of scale is 8 pages per interval.

Step 3: Answer Question 2

Question 2: Write the names who have read less than 40 pages.

I will compare each person's page count to 40:
- Adam: 40 (not less than 40)
- Maria: 24 (less than 40)
- Scott: 64 (not less than 40)
- Frank: 32 (less than 40)
- Linda: 56 (not less than 40)

Therefore, the people who have read less than 40 pages are Maria and Frank.

Step 4: Answer Question 3

Question 3: How many pages do Frank, Maria and Scott read in all?

I will add the page counts for these three individuals:
- Frank: 32
- Maria: 24
- Scott: 64

Total = 32 + 24 + 64 = 120 pages.

So, Frank, Maria, and Scott read 120 pages in all.

Step 5: Answer Question 4

Question 4: If Adam and Linda read the same book, how many more pages does Adam read to reach Linda?

This question asks for the difference between Linda's and Adam's page counts.
- Linda: 56 pages
- Adam: 40 pages

Difference = 56 - 40 = 16 pages.

Therefore, Adam needs to read 16 more pages to reach Linda.

Final Answers:

1. The unit of scale used is 8 pages.
2. The names who have read less than 40 pages are Maria and Frank.
3. Frank, Maria, and Scott read 120 pages in all.
4. Adam needs to read 16 more pages to reach Linda.
