Respuesta :

1 yard=36".
25 yeards = 25*36" = 900"
3 rolls = 3*900 =  2700"
Each piece must be 22" long, so the number of pieces
= 2700/22 = 122 pieces (2684") with 16" left over.

Erika has three pieces of ribbon, each of 25 yards' length.

Then in total she has 3·25=75 yards of ribbon.

Since 1 yd = 36 in, then 75 yd = 75·36=2700 in.

Now she needs to cut pieces that are 22 inches long, thus

[tex]2700:22=122\dfrac{16}{22}[/tex] pieces.

Answer: she can cut from the three pieces of ribbon 122 pieces that are 22 inches long.
