Answer:
1/4 feet long should each pieces be.
Step-by-step explanation:
Unit rate defined as the rates are expressed as a quantity of 1 such as 3 miles per second or 4 km per hour
As per the statement: Becky has a board that is 2 and 3/4 feet long.
⇒ Length of a board = [tex]2\frac{3}{4} =\frac{11}{4}[/tex] feet
Also, she need to cut the board into 11 pieces.
by unit rate definition:
[tex]\text{Unit rate per pieces} = \frac{\frac{11}{4} }{11}[/tex]
or
[tex]\text{Unit rate per pieces} = \frac{11}{4} \times \frac{1}{11} = \frac{1}{4}[/tex]
Therefore, 1/4 feet long should each pieces be.
