Allana 3/5 used yard of fabric to make a scarf. can she make 2 of these scarves with 1 7/10 yards of fabric, and why?

One scarf takes 3/5 of a yard. Two of these takes 6/5 of a yard.  If we put the 1 7/10 into an improper fraction we would get 17/10. So in order to compare the two fractions, the 6/5 and the 17/10, they have to have the same denominator. 6/5 can be rewritten as 12/10.  12/10 is less that the 17/10 you have, so yes you can make two scarves with that amount of fabric.

The answer is a because i went through all the other ones that it didn’t come out right

The answer is 25uthere is no v in the question
