Answer:
Each piece will be 5 inches long and the total number of pieces will be 22
Explanation:
For all the pieces to be of the same length, it means the chosen length must be a number which is a factor of both 45 and 65
The number which is the same factor as both asides 1 will be 5
So he intends having the length of each of the pieces to be 5 inches each
In the 45 inches, the number of pieces he will get will be 45/5 = 9 pieces
In the 65 inches, the number of pieces he will get will be 65/5 = 13 pieces
The number of total pieces will be 13 + 9 = 22 pieces
