Question

how many Board of length 1 integer1by 2feet can be cut from a piece of wooden log that measure 22 integer 1 by 2 feet in length ?​

Answer 1

Answer:

15 boards of given length can be cut from wooden log.

Step-by-step explanation:

Given:

Length of Board = $1\frac{1}{2}\:feet$

Length of Wooden Log = $22\frac{1}{2}\:feet$

First we convert length in improper fraction.

Length of Board = $1\frac{1}{2}=\frac{1\times2+1}{2}=\frac{3}{2}\:feet$

Length of Wooden Log = $22\frac{1}{2}=\frac{22\times2+1}{2}=\frac{45}{2}\:feet$

Number of board = $\frac{45}{2}\div\frac{3}{2}=\frac{45}{2}\times\frac{2}{3}=\frac{45}{3}=15$

Therefore, 15 boards of given length can be cut from wooden log.

Answer 2

Answer:

Step-by-step explanation:

Length of Board = 1 1/2 = 3/2 feet

Length of Wooden log = 22 1/2 = 45/2

feet

Number of board can be cut = 45/2 ÷

3/2

= 45/2 × 2/3

= 45/3

= 15 boards

Therefore,15 boards can be cut from a piece of a wooden log that measures 22 1/2 feet in length
