Question

Susan uses 15 rolls of ribbon to decorate 10 wedding baskets. Each roll of ribbon is


`5 (3)/(8)`
yards long. After she decorates the baskets, she decides to cut off another

`(3)/(4)`
yard from the ribbons of each basket. Write and simplify an expression to find out how much ribbon was used on the baskets.

Answer 1

Amount of ribbon used =
`73 (1)/(8) yards` = 73.125 yards.

Step-by-step explanation:

Number of ribbon rolls = 15

Number of wedding basket = 10

Length of 1 ribbon roll =
`5(3)/(8)=(5*8+3)/(8) =(43)/(8)` yards.

Total length of 15 ribbon roll =
`15*(43)/(8) =(645)/(8)`yards.

Length of ribbon cutting from each basket =
`(3)/(4)`yards.

Total length of ribbon cutting from 10 baskets =
`10*(3)/(4)=(15)/(2)` yards

Amount of ribbon used

`=(645)/(8)-(15)/(2)=(645)/(8)-(15*4)/(2*4)=(645)/(8)-(60)/(8)\\ \\ =(585)/(8) =73 (1)/(8) yards`

Amount of ribbon used =
`73 (1)/(8) yards` = 73.125 yards.
