Question

Bria needs 64 yards of ribbon for her craft project. If she has 3 rolls of ribnon, each with 3/5 roll left. If ribbon comes in 25 yards wil she have enough ribbon

Answer 1

She will have 45 yards of ribbon which isn't enough.
To find how much ribbon each roll has you need to find how much 1/5 of 25 yards is so you do 25 divided by 5 which is 5 and since it's 3/5 you do 5*3=15. each roll has 15 yards so 15*3 is 45 yards.

Answer 2

First, we have to calculate how much ribbon is left over on each roll in yards.  Write it like this:

3/5(25) = 15

One roll has 15 yards of ribbon left.  However, there are 3 rolls left over:

3(15) = 45

She has 45 yards of ribbon left, which, unfortunately, is not enough for her craft project.  To meet the project's ribbon requirements, she will need to purchase another roll (25 yds) of ribbon.
