Sophina brought 3 yards of trim to put around a rectangular scarf. she does not want the scarf to be wider than 12 inches or narrower than 6 inches .using whole numbers , if she uses all the trim, what are the possible dimensions of her scarf in inches.

3 yards equal 108 inches you can split it in half and get 54 then see how many 12 go in to it and that would be 4 and there would be 6 left over. then we have 54 and see how many 6 can go into it then add 6 more then that would equal 10 6
so that means we would have four twelths and ten sixths

She should use 12/3 to measure
