b) Find the length of the piece of blue ribbon that Linda cut off.

Answer 1

ANSWER


`a) (8)/(5) m`


`b) (2)/(5) m`



Step-by-step explanation


The length of Linda's orange ribbon is


`= 2m`
a)

The length of the blue ribbon is


`= (4)/(5) * 2m`


`= (8)/(5) m`


The length of the blue ribbon before it was cut is

`= (8)/(5) m`
Or


`= 1 (3)/(5) m`


b)

The piece of blue ribbon Linda cut off is


`= 25\% \: of \: (8)/(5)`



`= (25)/(100) * (8)/(5) m`


Cancel the common factors to get,


`= (5)/(100) * (8)/(1) m`



`= (40)/(100) m`


`= (2)/(5)m`

The piece of the blue ribbon Linda cut off
is


`(2)/(5) m`
long.
