Answer 1

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

Answer 2

If the following yards are: 4/5yd ; 3 1/2yd

This means Yu bought 1; 4/5yd and 2; 3 1/2yd

and Elena bought 5; 4/5yd and 1; 3 1/2yd

Reason: according to the data there is a certain amount of piece they each need plus it must be inbetween 7-9 yards. If you do the math this is the only possible way to calculate the answer.
