Given: Yu, Nailah, and Elena each bought between 7 and 9 yards of ribbon  Yu bought 3 pieces of ribbon. Nailah bought 5 pieces of ribbon. Elena bought 6 pieces of ribbon.
To find: Who can buy which ribbon
Solution:
Ribbon Sizes
1 2/3 = 5/3  yard
4/5  yard
3 1/2  = 7/2 Yard
Yu, Nailah, and Elena each bought between 7 and 9 yards of ribbon
Yu bought 3 pieces of ribbon
=> 3 * 5/3  = 5
   3 * 4/5  = 2.4
   3 * 7/2   = 10.5
Nailah  bought 5 pieces of ribbon
=> 5 * 5/3  = 8.33
    5 * 4/5  =  4
    5 * 7 /2   = 17.5
Elena bought 6 pieces of ribbon
=> 6 * 5/3  = 10
   6 * 4/5  = 4.8
   6 * 7 /2   = 21
Only value between 7 & 9 is 5 * 5/3  = 8.33
hence Nailah only can buy 1 2/3 = 5/3  yard ribbon
or there is some mistake in the data
