Answer:
[tex]2\ ft\ 7\ in[/tex]
Step-by-step explanation:
we know that
To find the difference convert the dimensions to inches
Remember that
[tex]1\ ft=12\ in[/tex]
so
katie's younger sister hight is
[tex]2\ ft\ 9\ in=2*12+9=33\ in[/tex]
katie's hight is
[tex]5\ ft\ 4\ in=5*12+4=64\ in[/tex]
Find the difference
[tex]64\ in-33\ in=31\ in[/tex]
Convert to feet and inches
[tex]31\ in=31/12=(24/12)+(7/12)=2+(7/12)=2\ ft\ 7\ in[/tex]
