Respuesta :
alrighty, positive divided by negative=negative so the end result is negative
disregard sign for now
convert to improper fractions
2 and 1/2=2+1/2=4/2+1/2=5/2
1 and 3/4=1+3/4=4/4+3/4=7/4
so
(2 and 1/2)/(1 and 3/4)=(5/2)/(7/4)=(5/2)(4/7)=20/14=10/7=7/7+3/7=1+3/7=1 and 3/7
but don't forget the sign is negative so -1 and 3/7
