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

Answer 1

ANSWER

$a) \frac{8}{5} m$

$b) \frac{2}{5} m$



EXPLANATION


The length of Linda's orange ribbon is

$= 2m$
a)

The length of the blue ribbon is

$= \frac{4}{5} \times 2m$

$= \frac{8}{5} m$


The length of the blue ribbon before it was cut is
$= \frac{8}{5} m$
Or

$= 1 \frac{3}{5} m$


b)

The piece of blue ribbon Linda cut off is

$= 25\% \: of \: \frac{8}{5}$


$= \frac{25}{100} \times \frac{8}{5} m$


Cancel the common factors to get,

$= \frac{5}{100} \times \frac{8}{1} m$


$= \frac{40}{100} m$

$= \frac{2}{5}m$

The piece of the blue ribbon Linda cut off
is

$\frac{2}{5} m$
long.
