There are 36 feet of ribbon in
12 packages. How many feet of
ribbon are in 21 packages?
feet

63 feet of ribbon

Step-by-step explanation:

First, you find the unit rate by dividing 36 by 12. That gets you 3 feet of ribbon per package. Since you need to find how many feet of ribbon are in 21 packages, you multiply 21 and 3. 21x3= 63

36/12 = x/1

36/12=3

3/1

3*21=63

1*21=21

63/21

there are 63 feet of ribbon in 21 packages
