Answer: Ibrahim's book is 0.74 feet longer than his marker.
Explanation:
In order to solve the exercise, both lengths must be in the same unit.
Then, you can make the conversion from centimeters to feet.
First it is important to remember the following:
![1\ ft=30.48\ cm](https://img.qammunity.org/2021/formulas/mathematics/middle-school/1r6kxzhe9dvvlbmx92fv8m0skyfdw55q28.png)
Knowing this, you can convert 8 centimeters to feet. This is:
![(8\ cm)((1\ ft)/(30.48\ cm))=0.26\ ft](https://img.qammunity.org/2021/formulas/mathematics/middle-school/zrwy1ijuobbmnzcl0wno8y4hu1lmata9xz.png)
As you can notice, Ibrahim's marker is smaller than his book.
Finally, you need to find the difference between the length of Ibrahim's book and the length of his marker by subtracting them:
![1\ ft-0.26\ ft=0.74\ ft](https://img.qammunity.org/2021/formulas/mathematics/middle-school/pemy0kipctz6u49icq8gkancb30b95lh0k.png)
Therefore, you can conclude that Ibrahim's book is 0.74 feet longer than his marker.
