Becky has a board that is 2 and 3/4 feet long. She needs to cut the board into 11 pieces of equal length. How long should each p

zzz [600]

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 = $2\frac{3}{4} =\frac{11}{4}$ feet

Also, she need to cut the board into 11 pieces.

by unit rate definition:

$\text{Unit rate per pieces} = \frac{\frac{11}{4} }{11}$

$\text{Unit rate per pieces} = \frac{11}{4} \times \frac{1}{11} = \frac{1}{4}$

Therefore, 1/4 feet long should each pieces be.
