Question

Jessica used 2/3 yard of fabric to make a scarf. Can she make 2 of these scarves with
1 3/4 yards of fabric, and why?

Answer 1

Yes because 
1 3/4 is 7/2 and 2/3+2/3=4/3

So yes he can 
Hope this helps :-P

Answer 2

Yes, you can. If it requires 2/3 yards of fabric to make one scarf, it requires 1 1/3 yards of fabric to make two scarves. So, by having 1 3/4 yards of fabric, you have enough to make 2 scarves.
