Question

Use the line plot to answer the question.

Two students spend $1\frac{1}{2}$ hours reading and three students spend $2\frac{3}{4}$ hours reading. What is the difference in time spent reading?

Answer

When we subtract mixed numbers we subtract the whole numbers by the whole numbers and the fractions by the fractions.

$\frac{3}{4}-\frac{1}{2}$ in order to subtract fractions we need to make common denominators.

$\frac{1}{2}\times\frac{2}{2}=\frac{2}{4}$

$\frac{3}{4}-\frac{2}{4}=\frac{1}{4}$

Compare your answer with the correct one above

Question

Use the line plot to answer the question.

How many hours do most students spend reading?

Answer

There are x marks above $2\frac{1}{2}$ , which is the most marks above our data set numbers.

Compare your answer with the correct one above

Question

The line chart shows how many hours each student in a class spends reading each week. How many hours, on average, do the least number of students spend reading each week?

Answer

There is only x mark above $1\frac{1}{4}$ , which is the least in our data set.

Compare your answer with the correct one above

Question

Use the line plot to answer the question.

What is the difference between the longest time spent reading and the shortest time spent reading?

Answer

The shortest time spent reading is hour, and the longest time spent reading is hours. We can subtract to find the difference.

Question

Use the line plot to answer the question.

One student spends $1\frac{1}{4}$ hours reading and three students spend $2\frac{1}{4}$ hours reading. What is the difference in time spent reading?

Answer

When we subtract mixed numbers we subtract the whole numbers by the whole numbers and the fractions by the fractions.

$\frac{1}{4}-\frac{1}{4}=0$

Compare your answer with the correct one above

Question

Use the line plot to answer the question.

Three students spend $2\frac{1}{4}$ hours reading and five students spend $2\frac{1}{2}$ hours reading. What is the difference in time spent reading?

Answer

When we subtract mixed numbers we subtract the whole numbers by the whole numbers and the fractions by the fractions.

$\frac{1}{2}-\frac{1}{4}$ in order to subtract fractions we need to make common denominators.

$\frac{1}{2}\times\frac{2}{2}=\frac{2}{4}$

$\frac{2}{4}-\frac{1}{4}=\frac{1}{4}$

Question

Use the line plot to answer the question.

Two students spend $1\frac{1}{2}$ hours reading and four students spend $1\frac{3}{4}$ hours reading. What is the difference in time spent reading?

Answer

When we subtract mixed numbers we subtract the whole numbers by the whole numbers and the fractions by the fractions.

$\frac{3}{4}-\frac{1}{2}$ in order to subtract fractions we need to make common denominators.

$\frac{1}{2}\times\frac{2}{2}=\frac{2}{4}$

$\frac{3}{4}-\frac{2}{4}=\frac{1}{4}$

Question

Use the line plot to answer the question.

Four students spend hours reading and one student spends $1\frac{1}{4}$ hours reading. What is the difference in time spent reading?

Answer

When we subtract mixed numbers we subtract the whole numbers by the whole numbers and the fractions by the fractions.

$\frac{1}{4}-0=\frac{1}{4}$

Question

Use the line plot to answer the question.

Two students spend $2\frac{3}{4}$ hours reading and one student spens $1\frac{1}{4}$ hours reading. What is the difference in time spent reading?

Answer

When we subtract mixed numbers we subtract the whole numbers by the whole numbers and the fractions by the fractions.

$\frac{3}{4}-\frac{1}{4}=\frac{2}{4}$

Compare your answer with the correct one above

Question

Use the line plot to answer the question.

Two students read $1\frac{1}{2}$ hours, hours, and $2\frac{3}{4}$ hours. What are all of these times added together?

Answer

When we add mixed numbers we add the whole numbers to the whole numbers and the fractions to the fractions.

$\frac{1}{2}+\frac{3}{4}$ in order to add fractions we need to make common denominators.

$\frac{1}{2}\times\frac{2}{2}=\frac{2}{4}$

$\frac{2}{4}-\frac{3}{4}=\frac{5}{4}$

$\frac{5}{4}=1\frac{1}{4}$

$5+1\frac{1}{4}=6\frac{1}{4}$

Compare your answer with the correct one above

Question

Use the line plot to answer the question.

Three students read hour and $2\frac{1}{4}$ . What are these times added together?

Answer

When we add mixed numbers we add the whole numbers to the whole numbers and the fractions to the fractions.

$0+\frac{1}{4}=\frac{1}{4}$
