Question

Misaki cut some wood for a bookcase she is building.She needs to find how many 1/3 ft boards she can make from a 5 ft board.Explain how to model with fraction bars to solve the problem.

Answer 1

Answer:

Sample Response: Model the 5 wholes as five 1s. Now add the fraction bars to show that three 1/3s fit in each whole. Count the 1/3s. Fifteen 1/3 ft boards can be cut from a 5 ft board.

Answer 2

Answer: There are 15 boards that she can make from a 5 ft board.

Step-by-step explanation:

Since we have given that

Length of a board = 5 ft

Length of board she can make from the above board is given by

$\frac{1}{3}\ ft$

We need to find the number of boards she can make from a 5 ft board.

According to question,

$\text{Number of boards}=\frac{5}{\frac{1}{3}}\\\\\text{Number of boards}=5\times 3\\\\\text{Number of boards}=15$

Hence, there are 15 boards that she can make from a 5 ft board.
