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

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.

Explanation:

Answer 2

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

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

`(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}=(5)/((1)/(3))\\\\\text{Number of boards}=5* 3\\\\\text{Number of boards}=15`

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