Explanation:

behind the seat#=2 3/5# quarts given

on the shelf#=3 2/3# quarts given

truck holds #12 3/4# quarts given

#:.=12 3/4-(2 3/5+3 2/3)#

#:.= 12 3/4-(13/5+11/3)#

#:.= 12 3/4-(39+55)/15#

#:.=51/4-(94/15)#

#:.=51/4-94/15#

#:.=(765-376)/60#

#:.=389/60#

#:.=6.483333333# quarts

#:.=6.483# quarts to the nearest 3 decimal places

1 imperial quart #= 2# pints

#0.48333333# quart #=0.483333333/1 xx 2=0.9666666#
