Answer:
<em>Strips should be </em><em>1.5 ft wide.</em>
Step-by-step explanation:
Given:
Width of 1st piece = 6 ft
Width of 2nd piece = 7.5 ft
To find:
To find the maximum width possible to make strips of equal size from both the pieces.
Solution:
This problem can be visualized as if we are given two numbers and we have to find the Highest common factor for both of them i.e. HCF of 6 and 7.5 will be our answer.
Let us try to factorize the given factors:


The common factors are highlighted above as underlined.
Therefore, the answer is 3
0.5 = <em>1.5 ft </em>
<em></em>
<em>Strips should be </em><em>1.5 ft wide.</em>
