Answer:
[tex]4\frac{3}{4}[/tex] feet is the height of Ellen's sister.
Step-by-step explanation:
Let the height of the sister of Ellen is = h feet
Ellen has the height = [tex]5\frac{1}{2}[/tex] feet
≈ [tex]\frac{11}{2}[/tex] feet
Since her sister is [tex]\frac{3}{4}[/tex] foot shorter than Ellan.
So, h = [tex]\frac{11}{2}-\frac{3}{4}[/tex]
= [tex]\frac{22-3}{4}[/tex]
= [tex]\frac{19}{4}[/tex] feet.
= [tex]4\frac{3}{4}[/tex] feet
Therefore, [tex]4\frac{3}{4}[/tex] feet is the height of Ellen's sister.
