Jabar used fraction strips to model the difference of 7/12 - 1/6. Which represents the difference?
A. seven 1/12 strips
B. one 1/12 strip
C. two 1/12 strips
D. five 1/12 strips
7/12 - 1/6 = 7/12 - 2/12 = ?
To find the difference of two fractions, you can use fraction strips to model them.
First, let's understand how to model 7/12 using fraction strips.
To represent 7/12, you would need to use seven 1/12 strips. Each strip represents 1/12. Since we have 7/12, we would need seven 1/12 strips.
Now, let's understand how to model 1/6 using fraction strips.
To represent 1/6, you would need to use one 1/6 strip.
To find the difference between these fractions, subtract the model of 1/6 from the model of 7/12.
Subtracting one 1/6 strip from seven 1/12 strips would leave you with five 1/12 strips.
Therefore, the correct answer is D. five 1/12 strips.
