Question

Sally has 20 feet of ribbon to use to cut the ribbon in the equal-sized links to make bracelet she wants to compare how many bracelets you can make if she uses different links right algebra expression that Sally can use to figure out how many bracelets you can make if she cuts the ribbon into a 7 and 1/2 inch or 6 and 3/4 inch length

Answer 1

1) 32 bracelets if she cuts the ribbon into a 7 and 1/2 inch.

2) 35 bracelets if she cuts the ribbon into a 6 and 3/4 inch.

Explanation:

1) Length of the ribbon = 20 feet = 240 inches

1 foot = 12 inches

Length of the ribbon required to make a bracelet =
`7(1)/(2)=(15)/(2)inches`

Let the number of bracelets Sally can make from 20 feet ribbon be x.

`x=(240 inches)/((15)/(2)inches)=32`

32 bracelets if she cuts the ribbon into a 7 and 1/2 inch.

2) Length of the ribbon = 20 feet = 240 inches

1 foot = 12 inches

Length of the ribbon required to make a bracelet =
`6(3)/(4)=(27)/(4) inches`

Let the number of bracelets Sally can make from 20 feet ribbon be x.

`x=(240 inches)/((27)/(4)inches)=35.555\approx 35`

35 bracelets if she cuts the ribbon into a 6 and 3/4 inch.

Answer 2

The 20 feet of ribbon could be cut into:
· 7 1/2 inch pieces
· 6 3/4 inch pieces
There are 12 inches in 1 foot.
12f = i
The expression could be:
12f ÷ 7 1/2
OR
12f ÷ 6 3/4
Hope this helps!
