Answer:

\(\frac{3}{8}\) yards

Step-by-step explanation:

Length of the piece of the ribbon = \(\frac{3}{4}\) yards

Nora will use \(\frac{1}{2}\) of it to make a bow

i.e \(\frac{1}{2}\) of  \(\frac{3}{4}\)

Now the actual length of the ribbon will she use for the bow can be calculated  as :

= \(\frac{1}{2} *\frac{3}{4}\)

= \(\frac{3}{8}\)

Therefore, the length of the ribbon will she use for the bow = \(\frac{3}{8}\) yards
