Answer:
Option B. 20 pieces
Step-by-step explanation:
The length of a strip of wood = 78 inches
This strip of wood is to be cut into pieces = [tex]3\frac{3}{4}[/tex] inches
We have to calculate how many pieces can be cut.
So first we convert mixed fraction to proper fraction and then to decimal.
[tex]3\frac{3}{4}[/tex] = [tex]\frac{15}{4}[/tex] = 3.75 inches
Now we divide 78 inches to 3.75 inches.
78 ÷ 3.75 = 20.8 pieces
we got 20 pieces of [tex]3\frac{3}{4}[/tex] inches.
Option B. 20
