Yolanda runs [tex]1\frac{3}{4}[/tex] miles on Saturday and [tex]2\frac{1}{2}[/tex] miles on Sunday.
So, she used fraction strips to model the total distance she ran.
As we know for calculating the total distance we always add the distance which is given.
So, [tex]1\frac{3}{4}[/tex] and [tex]2\frac{1}{2}[/tex] have a common denominator that is [tex]\frac{1}{4}[/tex].
From here we conclude that Yolanda needs a common denominator to add the fraction.
The correct answer is option (b) she needs a common denominator to add the fractions.
