Change=new-original

change=32 and 1/4-20 and 5/6

32 and 1/4-20 and 5/6=

32+1/4 - (20+5/6) =

32+1/4-20-5/6=

32-20+1/4-5/6=

1/4 and 5/6

LCD=12

1/4 times 3/3=3/12

5/6 times 2/2=10/12

32-10+3/12-10/12=

12-7/12=

11+12/12-7/12=

11+5/12

the turtle went down so the change is negative

the change is - 11 and 5/12 inches
